Those screenshots look damn good, I had no idea the original BD looked like that either. For some reason I had it in my mind that it was a bad transfer. So, yeah, I guess the biggest draw for this release are the extras? Sort of like Dr. Strangelove in that regard, except not as compelling. I really like the cover art though, it would make for a nice poster.
edit: The artist has the original art without the cover treatment, as well as some original sketches for it on his instagram
