The gfx sensor is just a modern Sony sensor with the equivalent of about 30mp pixel density.
It doesn't even have Fujis silly xtrans filter
A very good thing I readed about this camera is that, once the highest physical ISO is reached, it does not stores clipped data as Canon/Nikon and likely Sony do (instead it places a tag in the raw file indicating the required digital push, to be taken into account by the converters). So huge ISO levels are really usable and keep the DR. I don't know if other MFD also do the same. I prefer to never run above ISO 6400 in my 6D, and in exchange the camera LCD becomes less useful (dark) when severely underexposing.

That's true as you can see in the side-effect this has on the Photographic Dynamic Range (PDR) measurement:

This is not the only camera to do this, just a prominent example.

How do you "fix" this?
By understanding that DPreview doesn't really sanction using their own test scene to test for sharpness across cameras or even systems (they don't control a number of variables at play), particularly away from the centre.

Something closer to center.
I believe that the A9 files you see in the DR comparison test were taken before DPreview noticed that they had a problem with the A9's test scene files focusing.
Not that I particularly want to defend the A9 or anything, just that I wouldn't really evaluate sharpness between cameras with DPreview's test scene methodology.

Okay ... if the A9 shots are noted as flawed by the tester ... well, hopefully they'll fix that then.
Actually I think that they may have, in a hurry, left some sharpening with the 6DII files. When I manipulated the files myself, I didn't find that much difference besides chromatic aberrations (which I believe may impact perception of sharpness ?).

I wondered about that as a possibility for the variance. The degree of diff is seemingly narrowed in your full comps.
Once brought to the same size, there might remain a modest difference (absolute / perceptual) ... i.e. not the glaring diff above.

The DPR test scene isn't controlled for sharpness. Different models use different lenses (though the same lens is typically used amongst bodies from the same mfg.). Also using the comp button to resize the preview to the lowest common resolution typically messes with the sharpness.
What mostly highlights this comparison is that AA filters are a necessity. The proper deconvolution sharpening techniques totally recover the (non truly lost) information while no false signal enters in the image. Hoping that Canon "resists" the only-non-AA marketing hype and the 5DS2 will still have an AA option. I know I'll be censured by this but... if more engineers were at the Canon product board perhaps even the 5DSR would not exist, but other companies seem to have not a single engineer on it.

So good high ISO is not incompatible with good DR on modern tech. And the cost of manufacturing a better sensor is the same (otherwise, Canon would have not used them in the 800D at no price increase). But on FF has decided to use the new feature as a market segmentation tool for this generation.
Are you saying this is intentional market segmentation? Do you have a source for this?
Honestly, this makes no real sense to me. Not when much less expensive cameras like the 80D and EOS M5 share (some of) the expanded dynamic range present in the 5D Mark IV and 1DX II.
I would bet dollars to donuts that this is due to nothing more than Canon's product planners simply failing to prioritize this as an important feature for 6D users, coupled with a desire to leverage existing tech, since it is costly to keep creating new sensors. Despite what Canon has stated publicly, it's likely this sensor was derived from the existing 6D sensor because it was deemed expedient, and this explains why it does not share the high dynamic range improvements.
I personally think they should simply have used the 5D Mark IV sensor, as the cameras are differentiated in plenty of other ways. The fact that an all-new 26MP was deemed necessary *is* a decision no doubt driven by market segmentation, so I'll give you that. The limited dynamic range, I think, is probably just a byproduct of their other choices.

I am really stunned by this threat to "leave Canon" over the release of this camera. Some may take those posts seriously, but I can't help but question a sincere intent on letting a release of a camera model influence their camera choice that seriously, or not.
I am becoming a little tired of patronising statements to the effect that no-one who says that they will move from Canon will actually do so. People do move, and for some people the launch of a disappointing camera will be the trigger for the move.
In my own case, I have been waiting for several years to replace my 5D MkII, and the principal reason is to have improved DR. I had hoped that the 6D MkII would be the answer, but that was not to be. It is vanishingly unlikely that Canon will release a camera that will meet my needs for at least 2 - 3 years, and I have been waiting long enough. So will now be purchasing be a Sony body, and a Metabones adapter for my Canon lenses. If Canon comes up with something more suitable in the future, I will consider moving back to Canon bodies. But please do me the courtesy of believing me when I say that I will not be buying a 6D MkII, and will instead be buying a Sony body.
Some people feel it is right to be unswervingly loyal to a brand; others will assess the situation from time to time, and switch to equipment that they believe better suits their individual requirements. Neither approach makes anyone a better or worse photographer. Live and let live!

I'm not doubting your personal story here, it's just that we hear the same thing from a lot of people at the release of a new camera, and they are just venting, and it's the same as saying you're going to move out of the country if so and so gets elected. I wasn't trying to single you out, I was just making a broad observation.
I'm sure that some people do switch, but not all of them for sure. I didn't mean to seem like I was calling you out for being deceptive, I was just making a broad statement. Good luck in your Metabones experience. I was seeing some write ups on that system and you can produce some great images with it.

It seems like Nikon has a great showing when it comes to the best selling, meaning the ones people buy, and consequently use, the most. I was pretty amazed to see Nikon putting up a good showing. It was 5 Canon and 5 Nikon in the top 10 most purchased/used cameras. I was under the impression Nikon was in financial trouble, as they have been changing their game towards smaller cameras lately I understand. I have checked a bunch of different sites of the best selling documented DSLR's and it looks like it's all Canikon except for a few stray Pentax's. That surprised me. The Canon 6D Mk II will be on the top soon enough, that's a given.
