Yes, but it's not really about that is it? You will still perceive enough detail during gameplay. The appearance of the game IN MOTION is what is most important, in the end, and post-processing adds greatly to that. Stripping out depth of field and motion blur is not a good thing. I'm way into motion blur and post effects, though.Going by this image, where texture detail is almost completely lost, I'd say yes.
I'm not saying it looks bad. But detail has been lost. And not in a manner that makes sense to be attributed to DOF or Motion Blur, or anything else, when all the other details resolves so sharply.
The Xbox One X version we played had motion blur in full, though, but depth of field was modified. Not sure why but that's the current state. I expect that will change by release.
Also, why is everyone focusing on the face? We know that's a dynamic element. I think the jacket textures are far more interesting.
In the end, I'm sure the Xbox One X version will be using the PC's highest quality texture option which makes perfect sense as it has the available memory for it. There's nothing mysterious about it.
We also know that enriched mode enables things like tessellation which are absent in the native 4K mode.
