The game almost certainly doesn't have a temporal upscaler. Without decent motion vector data, temporal upscalers break, and I doubt Nintendo/Monolith Soft wrote code for motion-vector tracking beyond what would've been there for a 2015 Wii U game.
I think people are just noticing what happens when you upscale earlier deferred rendering titles without applying a TAA solution and just depend on SMAA instead.
You get specular shimmering and temporal instability. Plus Monolith Soft games always tend to have noticeable pop-in.
TAA introduces a lot of blur to the image, but it does solve these problems. And then DLSS/FSR2+ have improved upon thr problems TAA introduced, also introducing artifacts, but far less noticeable ones than shimmering and aliasing.
Edit: I expect XBC2 and 3 definitive editions to have DLSS because they already have Monolith's custom TAA solution and therefore motion-vector access.
