Some scenes look darker than they should (even more so since we're used to regular, relative "flat" raster), as the game has a really strong and weird Eye Adaptation + Vignetting going on. Even with a mod is hard to get rid off. Raster and RT are less effected, but path tracing manages to push it forward better.
In strong contrast, high dynamic range scenes is very obvious and annoying. Could be artistic, could be whatever, it happens less when there isn't such hard contrast.
First image is looking "up"/leveled somewhat, with the street in relative darkness. Second image is just looking down and the scene brightness up.
Below are a couple more pics. First is with Raster, second with path tracing. On the second image, right side up, where the blue is on the building, in the path tracing image the highlights are much stronger than in raster, so I'm not sure that the "darker" instances are due to path tracing (as in too few rays going around) or rather an artistic choice. I tend to lean towards the later.
