I was wondering about the possible PS5 version if it could be in the realm of possibility to have solid 4k60fps with playable characters having cinematic models used in-game. That alone would probably make this game one of the best looking launch games on next-gen.
The hair in the trailer looks better than the hair in the game. Something about the way it's lit makes it look more like hair from a CG movie, while the game hair looks like game hair. Also, the lighting and AO on foliage looks lower quality.
The animation downgrade could be memory limit or cpu perf limit. So they use less "natural" anm that uses less memory and or less cpu calculations (that are needed to smoothen the 'stitch' between animations and world objects).
IIRC ages ago when I tried a bunch of mods on skyrim vr, turns out the modded animation that looks way better is the culprit. My cpu single thread perf was too low.
