What I liked to see is that all the vfx elements from the motion pictures have been saved as well. Is the shot of the Klingon ship from heart of glory from Tmp? If so even those elements have survived!
Paramount did an utterly awful job with the movie blurays. I would like CBS to go do them right; remaster them at 4k+, recreate the vfx from the original elements so they all look as good as tng-HD (remove matt lines etc) and keep the grain intact - don't scrub it and make it look awful like the 5 min job paramount did.
