I know Lucasfilm usually does their own in house stuff, but they should have the people who restored Cinderella restore the OT theatrical cuts. Hand it off to Disney. For the first time that movie looks like film again in 4K. They should do that as little DNR as possible, and include the original audio. Just remove the garbage mattes but no other fixes.
That would be cool to see.
It also seemed that Lucasfilm may have their own OT theatrical cut scan, going on what some people say who watched the recent Icons Unearthed documentary. A small number of scenes appeared in their pre-1997 format in that doc. You have to wonder, or hope, that Lucasfilm or Disney have a scan ready for release. Or at least for internal use, and for highlighting that original theatrical work.
