That's pretty cool, The blue blacks are something that always bothered me about PG. Especially the cockpit shot of Luke looks much better.

And I think a new encode from the original files could improve the PQ quite a lot as well.

I would personally lose the rounded sides as well, since from what I understand they're a side product of the transfer and not a part of the original print, but I understand the desire to keep as much of the picture as possible. And whenever I watched PG, I always zoomed it in slightly to hide them, so I guess I can just continue doing that :-)
