Well, I think the point is that Harmy’s not shooting for any aesthetic other than “what it looked like in 1977”. So if it looked like a Technicolor trainwreck with inconsistent skin tones back then, success means that’s what it’ll look like here. If Han’s shirt was yellow in one scene and white in another in 1977 (which would be pretty normal due to interior lighting differences), correcting that would be revisionist.

I am assuming Harmy’s likely to use his professional scan of a low-fade theatrical print as a reference, like he dd with 2.5, but with a little more leeway around correction, since that reference wasn’t fully corrected, and with better tools for making all the various sources match that color timing, instead of eyeballing it and settling for close enough in many cases. If that’s the case, 3.x will look a lot closer to 2.5 than any home video presentation, simply because 2.5 got closer to theatrical colors than any home video presentation. But there’s always room for improvement.
