Vision Pro might not be able to match 8K but based on the specifications it should be able to hit a level of pixel fidelity close to 4K with an IMAX sized screen. The vast majority of movies exist with only 2K digital masters available, with quite a lot of "4K" content being upscaled. This is the case even with new releases. My local cinema, a rather big chain, still has 2K projectors in the vast majority of their theaters. For film and TV content I don't see the resolution of the Vision Pro to be problem. For desktop use where screens are usually smaller I guess we'll see how close it gets, but even if it doesn't hit full 4K fidelity, ~1440p at ~32" inches is still plenty usable, particularly if desktop real estate is unlimited.
There were plenty of large format standard definition sets, they were just either way too big (CRTs) or rear projection (worse picture quality, which is saying something for 480i). DVD is SD and was a dominant format for a significant amount of time after the rapid rise of HD flatscreens. TVs got big because the technology allowed for it without requiring TVs to be installed via forklift or crane, not because people didn't want a big picture.
I've used a bunch of headsets too and it baffles me when people with plenty of time wearing these bricks can't extrapolate those experiences out, it doesn't require a whole lot of imagination. The Quest 2/Pro aren't cutting edge and their UI is jank, but even with the shitty passthrough it's pretty clear (to me at least) how virtual screens can be useful based on my experience with them.
