I also concur that the 35mm scans look remarkably like the BD, with the teal shift being slightly revisionist however.
Celluloid and digital video color space are totally different things though, so was the BD an attempt with modern digital technology to try and mimic the original Eastman color release print?
Hard to say did they use the IP as reference. How faded were the obviously not first gen sources.
Same problem James Bond and Star Wars had go back to the OCN and lose the intended color timing, get an image too pristine and never intended for the theatrical movie going experience of the era.
