After all these years of reading and researching the 1997 restoration of star wars. My mind has come up with a little scenario for how the SE’s came to be… please tell me if what I think is remotely true.

O-negative was cleaned and scanned at 1080p or 2K?
was Color corrected/cleaned up ETC.
SE changes where added.
exported onto some type of Print for future restorations.
Every release since 97’ was based on that export print.

I’m not sure if that is right or wrong. please help me gain my sanity.
