Watching the Ray Tracing on/off side by side comparisons of this new game "Control" I never thought I'd say this but...
In some instances the Ray Traced scene looks less realistic than the vanilla rasterization version.
This is not even accounting for the whooping 50% decrease in performance but you know, not every damn water puddle is a freaking mirror in real life.
Ray Traced reflections is the less meaningful implementation of DXR (much prefer global ilumination) and in some cases devs are forcing it so much down our throats with water everywhere and mirror like reflections that it looks worse and less realistic than the rasterization version.

I would argue that it's unrealistic from a "why would this ever be here in the first place?" point of view, but not from an actually physically unrealistic point of view. Keep in mind where we're coming from and what the new thing is trying to improve.
As a semi-related example, people were so used to being able to hear softer sounds mixed in with gun shots and explosions that they thought Frostbite's audio mixing engine was bugged and couldn't keep up because the mixing engine would cut off quieter sounds if loud sounds were going off near you.
