MOTION/FRAME CHANGE COMPRESSION:
Looking into it a bit more, focused on a blu-ray disc case, hand-held moving camera about a bit, moving in and out of focus, so plenty of changes frame to frame.
Comparing ProRes HQ with NinjA to internal IPB looking frame by frame in PP there is a difference on some fast moving, defocused stuff the internal gets a weird painterly effect that is partly smooth and partly ragged while the Ninja 2 recording stays smooth. So frame by frame over stuff like that the external record looks a lot better.... at least peaked at frame by frame. Very clearly better. Having checked out how noticeable it is to the eye in real-time yet though.
Frame by frame, when things are wholesale changing the external recorder clearly gives better compression than the internal IPB (didn't compare ALL-I yet).
Again I need to see how noticeable it is in real life. Also having lots of entire frame changes during big motions or focus chnages probably aren't the most import things since everything will look blurry etc anyway. But perhaps not have a nasty half watercolor half sharp jaggy motion blur would make such things looks worse than maintain a smooth look. Frame by frame, for wholescale entire frame movements and changes there is no doubt the external compression holds up vastly better than the IPB internal. The ALL-I internal may hold up much better though than IPB to such things. I need to see if the ALL-I doesn't lose fine static details or have other issues though.

RED/WHITE TRANSITION:
External compression is less jaggy. Vertically white to red happens a bit more naturally and better with the external compression.
--------
BUT WEIRD:
On left to right the internal compressor seems to try to balance the change on both sides, maybe doing it a bit more on the right sides of transition types while the external seems to try to load up transitions on the left sides and in a less balanced fashion.
So with the external red and white and so on are less jaggy together and smoother on the external recording overall but OTOH the external gets somewhat more noticeable 'dark sharpening halo' looking effects each time going L to R that red has to hit white or yellow or that black has to hit red. With the internal those are actually less pronounced, less false fake artifact halos even if the transition lines are jaggier and when it does have these fake halos they tend to be more on the other side white going to red or red going to black.
Weird.
vertically the external handles color transitions better, but horizontally something about the internal does it almost seems to leave less noticeably artifacts in some sense.
Oddly when there is red before white going left to right, the ninja 2 ProRes HQ recordings seem to have a wide less saturated, darker area right before white that the internal recordings don't. Almost like it has LESS color resolution horizontally using the HDMI out recorder or that it is applies some sort of left edge sharpening for red into white Or maybe without the white jaggy in it makes for a darker edge and the 4:2:0 actually ironically makes a less smooth and yet more natural transition on those sides? Or maybe it is the internal compressor is placing the transition more in the middle and not totally left biased
Not sure if it is the Ninja 2, the ProRes HQ, Premiere Pro or the 5D3 but the external recoder is giving a dark, de-sat halo line on red to bright white transitions (not so much on white to red) going horizontally. The internal recorder is free of that transition artifact! A bit of a shame since otherwise you can see the external is holding up better on any motion and it has less jaggy red/white transitions at many angles.
Very, very odd. Why would the external ones seem to a giant seeming sub-sampling transition going from any sort of red to white left to right and the internal not?
I also see that black to pink gives a smear of pink black inbetween using the external recorder and yet using the internal it is mostly free of the smear!?!

COLOR/BRIGHTNESS SHIFTS:
I could swear the external recordings seem to clip on the brights a bit quicker. They seem a bit brighter overall Maybe applying the same colorista effect to each was no good, maybe the details in highlights were still there and I shouldn't have brightened it up as much. Need to look into it. Does it clip away more DR externally or just place thing differently.
The external also seems to be a bit green-ish cast compared to the internal. Although I see people complaining, I'm not sure the external is the wrong one though. The blue on the blu-ray case looks to have some green in the blue to my eye and that is what the external recording shows and yet the internal recording show the case to have more of a hint of purple to it than green tinge which seems less accurate. Unfortunately by the time I checked the lighting had change though so I need to re-check when I can view the case under the same color temp lighting as when the footage was taken.
