The Eastman print is a show print struck directly from the negative that was very rarely screened, so it has significantly more detail than any release print and is in wonderful condition, which is why it only took 6 months to restore.

The LPP is a couple more generations away from the negative, but should have all the color timing detail from the interpositive/internegative steps preserved that are likely just not there in the Eastman print.

Also, the LPP wasn’t scanned at 4K and is missing frames, plus is more damaged, so its value is primarily as a color reference to punch up the Eastman (4K83) print if people are so inclined.

But 4K83 is an accurate preservation of the Eastman show print, which is why (I think) the decision was made to preserve the colors as stored on it versus matching it to something like the LPP for the primary 4K83 release.

Williarob or ohteedee can correct me if I’m mistaken on any of this, of course.
