I'm reminded of this blog post[0] from 2017 about bad tone mapping in video games. A game can put all the work it wants into realistic puddle reflections, but it'll still scream "video game" to your eyes if the color grading is so out of whack that it couldn't possibly be a real scene. That post is focused on how it was done wrong so often in the early days of HDR.

This clip has lots of things that stick out to me as video gamey, but the color is on-point. I suspect that's a huge part of the realism.
