It’s arguably more typically considered an advancement in the realism of simulating a real life camera with an optical lens. Not the same thing as simulating human visual perception more realistically.

Games are trying to look more like movies, hence new technologies to simulate shallow DoF, lens flare, anamorphic lens artifacts etc. None of these really help make the game world look more like how a human might perceive them, they do all help make the game look like how a typical movie camera might have perceived the scene.

For sure shallow DoF simulation _could_ be used to try and make games more human perception like, but I don’t think I’ve ever seen the effect used this way - it’s virtually always used to simulate optical bokeh/out of focus areas to look more film like.
