Planet Earth is certainly a visual delight, but strictly from a picture quality perspective, its far from the best blu-ray quality that I have seen, IMHO. Same for Bladerunner. Here's a good reference list for the top blu-ray's, strictly from a picture quality persective.

Certainly, there's some subjectivity here, but this seems to be a pretty good reference list. There is a separate thread at the same site for best audio quality.
