Luke's tunic wasn't true white, or at least it didn't show up as such in the original color timing. A sort of sandy tan/yellow/gray, very slight but noticeable.

Jaitea's adjustment looks really good, that's close to the kind of timing I'd want to see on a perfect OUT Blu-ray.

I was just watching the Blu-ray of Close Encounters; I wasn't alive to see the film in the theater, but the color timing feels right, it feels like 1977. Due to similar negative/CRI fading issues, I believe that at least some of the transfer comes from an IP, so sometimes it looks kind of grainy (particularly in FX shots), but so what? It still looks like a movie from 1977. If only Lucasfilm was willing to give the OUT a transfer with that kind of fidelity to the original color timing...
