More evidence that this version use the 1997 special edition as its base, with subsequent changes being re-created fresh.
Which was always going to be the case since the o-neg itself was conformed to the SE edit of the movie back in ‘97.
Btw, I guess this means the initial scan (before they redid the ‘04 and ‘11 changes) was/is the 1997 version exactly as it existed back then. I’m not going to hold my breath, but this does at least mean they’ve now got that version scanned in at the highest possible quality, not to mention roughly 80% of the unaltered OOT camera negative as well.
IIRC, there was a rumor several years ago that every last piece of film in Lucasfilm’s vaults were being scanned in and catalogued. Perhaps this 19SE is just the tip of the iceberg.
