According to thedigitalbits TPM is a new scan which was also used for the 3D re-release (there’s still a lot of DNR in an attempt to blend the film elements and digital scenes) and AOTC and ROTS are based on the old 2K masters (they were shot in 1080p but mastered in 2K) but with additional upscaling and “film look” processing to bring them to 4K. The grades are also slightly different.
The Blu-Rays included in the new set are downscales of the new 4K master, not the same as the old blu-rays.
Thanks for the clarification!
Now the only question is whether or not buying the blu-ray only Skywalker Saga set means you get these 2019 transfers, or (presumably?) new artwork placed on the top of the 2011 Fox discs (?)
I wonder if the confusion is coming from people buying blu-ray only single disc versions, which ARE the 2011 discs just re-packaged, and have been on shelves for awhile now. From what I understand, the artwork for the new 4K single-disc releases is the exact same as the blu-ray only single-disc releases that preceded them, so maybe THAT’S where the confusion is coming in?
