Really it just makes an official restoration from Disney all the more conspicuous in its absence.

Lucasfilm has access to even better materials closer in the photochemical chain to the camera negative than the Academy’s 70mm blow-up, although the fact it’s in such good condition means it should probably be preserved if only because it could be the best remaining record of all the picture and sound differences in that version of the movie for all we know. That is of course unless this print is different still from the ‘77 blow-ups and conforms closer to the 35mm prints in terms of content.
