The guy with no name may be able to help find the bad shots. He worked on a remaster of the 2020 Blu-ray of Star Wars and fixed many of the known problems, including detail loss, static grain and displaced power windows.

Since his project was never officially released, but he is still active, you might ask him if he knows a list of problematic shots on the UHD Blu-ray or if he could even provide finished, fixed shots.
If you would like to find out more, here is the link to the project: https://originaltrilogy.com/topic/STAR-WARS-EPISODE-IV-2020-4K-blu-ray-Remastered-WIP/id/99662/
Maybe that would make the work for v3.0 a little easier. 😃
