I think the 35mm LPP shots are just objectively better than rotoscoped BD/GOUT hybrids. All you need to look at is the fact that in ROTJ v2.5, I replaced the BD footge with the LPP scan for an entire scene, which had no changes, just to improve the image quality - and sure, this scene was particularly bad on the BD but it shows that the 35mm shots, when properly cleaned up, sensitively sharpened (as they have to be in order to fit with the BD, which has tons of artificial sharpening applied) and color-corrected are nearly on par with the BD footage, which is so over-processed, it barely has more detail than 720p, even though it comes from an earlier generation print.

A lot of the shots I replaced with 35mm in ROTJ did look better on the BD, but not because they came from a 35mm print and the BD comes from a better source, but because they were recomposited on the BD and so they are supposed to be slightly lower quality than the BD in any version claiming to be the original.
