I understand this scripting of yours is one setting for the entire film, but I seriously recommend anyone color correcting the '06 bonus disc to treat at least the opening shot separately, as the '77 film element they spliced in have a vastly different white level (contrast) compared to the '93 LD-master.

I'm not entirely sure but I believe the splice occur right before the "A long time ago" text, the Fox logo and Lucasfilm logo is definitely from the '93-telecine.
