Looking at the link they posted of the comparison (https://youtu.be/P1b47UP6ZGI) I cannot believe how much worse the blueray looks. The whole frame turns bright magenta during every laser rifle burst in the opening sequence!

I also think it's very telling that a bunch of fans made something better than the professional effort, with a small fraction of the budget, and are distributing it almost as a public good to ensue that it remains accessible in pereptuity.
