The match is indeed pretty good, but grain, crushed blacks, and whites, are an issue for these types of algoritms. I think it could in principle be solved, by adjusting some of steep gradients in the color prediction.
The color prediction I did for Leia frame based on a 35 mm frame, is surprisingly close to a similar frame of Star Wars Legacy Edtion, that Mike Verta posted on his website.

I must admit, I really like these more saturated colors. They look really film like.
