Is there anything to suggest that the regraded Alien and YOLT are closer to the theatrical colours than the bluray or are they just timed to match older home video releases?
I believe Alien and YOLT are corrected for a natural-looking palette more than anything. kk650 makes the off-white whites white again. Thus, they are technically correct and not tinted.
YOLT unfortunately doesn't have its technicolor back yet but at least its better than both the DVD and BD. There's no pink tint, which makes flesh tones and whites weird.
