The thing is that the source I used has 100% perfect colors, as far as I’m concerned, but not great picture.
Using KK650 would be a step down in colors (just because his target is different, not because they’re poor), and a fair improvement in picture. I believe it’s abailable at something like 19GB, compared to Adywan’s 1997 SE project’s 13GB.
What would be a big upgrade in picture that would make it more acceptable to sacrifice the color grade would be something sourced from the BR and clocking in at something like 25-30GB.
