Photorealism is not just about making it look mundane

My wife is very good at pencil drawings, one of the favorites is 4 generations of the family next to each other in the same picture. Creating a big picture of a small faded photograph is a great art style.
What games should stop doing is faking photo realism by simulating all the flaws in camera lenses. Cut it out with the depth of field, motion blur, lens flares, bloom, fake hdr. Sure some of these exist in our visual system too, but my eyes are a whole lot better then the cheap cameras games try to simulate.
Keep all the properties of light and shadow, yyet enhance the visual quality instead of degrade it.
Kinda ironic that while photography has been using HDR to create hyperrealistic looking photographs, games have been trying to emulate cheap digital camera with the opposite HDR effect.

So many (photorealistic) art style choices for games, why make it look like a cheap documentary.
