The problem with all the home video releases is, that none are actually representative of the theatrical color grading. So, it's extrememely difficult to draw conclusions from any of them. The colors were pretty much regraded for every home video release, and the differences between them are sometimes very large.

I recently matched the bluray to the colors of most home video releases, and to a scan from a Technicolor IB print for two frames on the Tantive IV, and the differences are huge.
