It still doesn't mean that I can't make positive comments, as I did earlier comparing the two different covers. And simply declaring that one is not a fan of a film doesn't mean one can't say anything nice. I can list any number of positive things about Man of Steel as a piece of cinematic art...
Now, now. Be nice. Since this thread is about a video presentation of the film, and not the film itself, my thoughts about the film aren't especially relevant. And I'm not commenting here to rain on any fan of the film's parade.
I just looked at an image of it. Yeah, I guess the cover can be described as "striking", though it doesn't work that well for me. The Best Buy SteelBook cover looks much better, in my opinion.
Given that just before he says "Upgrade from Blu-ray - No", he says "Makes use of and works well in 4k - 2.5", I'm'a guess that he means it's not an upgrade (or not much of one).
