What master does the Disney+ version use? Is it the same as the 2011 master (or the 2011 master but upscaled)? Is it the 2011 master but at higher resolution? Or is it a new master entirely?
2011
Incorrect. It is a new tansfer of ANH, TESB, and ROTJ with different colors and a few differences. The changes cannot come from being recolored as they restore previously missing colors. I think TPM is as well and TFA likely is nearly identical, but unlike the Blu-Ray master (which had burned in English subtitles for all regions and languages) it has a clean image and you can turn the subtitles off. AOTC and ROTS have no color changes (makes sense since the digital file is the original image, not a film scan) and is likely upscaled to 4k.
Pretty sure they’re talking only about TPM, which if so, would be correct. It’s the 2011 version, but regraded for HDR.
But I’m most excited about this project because the current 4K master blows. Too much DNR.
