There’s one little background change that was made to TESB when it hit 4K that the Revisited version doesn’t have. On the 2011 Blu-Ray, in the three close-up shots where Luke’s X-Wing is sinking in the water, there’s a black section that’s cast over the top right corner. The 4K version fixed that by replacing the black section with more haze. You can see the differences here: https://www.movie-censorship.com/report.php?ID=137645
Is this change even worth applying to TESB:R when you get to working on the Blu-Ray?
To be clear, that’s not so much a “fix” as “the 4K version didn’t ruin the scan of the film in that particular way”.
So, it’s not really worth it?
I’m just saying it’s not a “fix”, it’s a choice of what scan he wants to use.
