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. 😃
In fact, on the ESB Despecialized forum I already told Harmy that TGWNN is working on that remastering of the 2020 Blu-Ray adding details that were erased by the strong DNR and that only exist in the 2011 BR, currently he is working on 4K77 remaster, but I could ask him for a list of scenes where the 2011 BR looks better to fix the 2020 one, although the best thing would be to rotoscope those elements that look better in the 2011 BR to add them to the 2020 BR, since they are usually background elements like the rubber walls of the Millennium Falcon, since other elements that are closer in the 2020 BR usually look better.
