I was looking at that newest Tantive test. It looks better than the original timing, but the problem with a lot of the pink/orange flashes and stuff like that is that it looks like they actually dialed down the highlights (and pumped up the saturation?) on those specific parts of the frame. Whereas the GOUT has clipped whites, a lot of the flash frames and explosions in the '04/'11, have almost *no* whites. Areas of the blaster-impact explosions that were highlights in the older transfers look almost indistinguishable from midtones in the newer ones, and look almost too colorful in relation to the rest of the image.
I'm also thinking of things like the sleeve of the Jawa applying R2's restraining bolt - that amorphous purple blob looks to me like some kind of digital color grading matte. And Harmy just spotted the brightening of Vader's face mask in that one scene.
