Those are all fair points, but I would challenge the claim of color accuracy. I’d say the colors of both are very good (and there are multiple color-timing options to choose from with 4K77 already). Personally I prefer the colors on 4K77 for a couple reasons. One, the original release was timed to match how the print actually looks. And two, while DeEd’s colors are good, they still occasionally suffer from the horrible color timing of the official BD’s creeping through in minor ways.

But really the difference in colors is so minor as to almost not even be worth arguing over. At least to me.
