I don't think this is a fair comparison. The DR of the Olympus image (before sundown) is much higher than the DR of the Sony image (after sundown). So the shadows and under-exposed areas of the Olympus image is much deeper to begin with, so quite naturally when you try to pull the detail out of the deeper shadow areas you will see a lot more noise.

Thanks. This actually made me think: how much different would this be between m4/3 and FF. So I went searching through my m4/3 images for photos with similar dynamic range, and here's what I came up with, which helps illustrate the point a bit.
First, m4/3. In this case, my E-M10 Mark II. this isn't the absolute best m4/3 sensor (though it's only 2 years old), but neither is the FF sensor I'm going to compare it to, so we should be on fairly equal footing.
This is what the RAW looks like with no processing:
Looks fine. Now, let's bring out those shadows....here's a +100 shadow adjustment in lightroom:
Hmm....you can see a lot of noise...let's see what it looks like up close:
Yuck. There's absolutely nothing usable in there. It's just mush, and the transitions are harsh and it's just not good. Now, a +100 shadow push is pretty significant....but.....
Now, let's take a look at the FF file.
The isn't the same file as the image I posted above, but it was taken a few seconds before.
Here's what it looked like in LR with no adjustments:
And...with a bigger exposure push...+1 stop overall exposure, plus +100 in the shadows (and -100 in the highlights):
And how do those shadows look?
Well, pretty darn clean.
