I've seen some of the color correction split screen comparisons on youtube. If anything those are great to point out just how bad the 2004 transfers were. I don't know if those are the final look or still in progress but there are a few cases where I think the part of the shot should stay blue.

In the Milennium Falcon. There's a bright wide light in the cockpit. One example is at 50 seconds above Leia's head. I'm pretty sure that's part is blue even on the gout.

Some of the exterior shots of the walkers. The sky looks like it loses too much of the blue hue with the color correction. This occurs at 29 37 49 & 53 seconds. Now I saw another comparison uploaded about 3 months later in October called Hoth Split Screen. It seems to be the same part but with different color correction. The sky appears to maintain it's proper blue color in this sample.
