[2022] Significantly downgraded graphics on PS4 Pro

This started occurring right around after TU15 - it appears that none of the intended high res models/textures are loading into the game. There was the occasional pop-in problem before the update, but nothing close to this. Since a few days ago, every location on the map is rendered with low-res and low-polygon models. Sometimes the models will improve slightly if I remain still for a few seconds, but most of the time I'm surrounded by blurry images and blocky geometry like in the screenshot below.

I've tried restarting the game, restarting the console, and rebuilt the database on the ps4, but it doesn't look like the problem is on my end. Is this a known problem with a fix in the works? I'd love to return to the beautiful detailed world in this game.
