If that’s the case, which honestly, it probably is, then the quality of it seems to be pretty bad. I’ll probably be sticking to the BD for Despecialized because at least there we know what changes were made to it and the quality seems comparable, if not better.
I don’t think the quality can really be assessed from a screenshot of 4K video streaming content. A comparison would have to be made with HD streaming, which in of itself has far less detail then the bluray. The real comparison can only be made with the eventual hard copy versions, but considering the generally poor quality of the bluray, I can’t imagine it won’t be significantly better than the 2004 master, particulary since the new master doesn’t seem to have the excessive sharpening of the 2004 versions. Additionally the 10 bit colors will provide much more dynamic range to work with, compared to the black crush ridden blurays.
