That's kind of Vegas in a nutshell, right? It's first and foremost about superficial glitz and glamour. Nothing wrong with that really, and they sure are good at it.
I saw Eagles at Sphere with my family (part of the fun of that trip was realizing that both of those entities explicitly [perhaps vehemently] do not use an article in the name and thus that is grammatically correct).
I agree that it is a very strange venue that doesn't seem to know what audience it's going for. Band culture, and generally the types of acts that play to a seated crowd, is more about the performance than over-the-top and overwhelming visual stimuli. Dance music culture, the people that love that, prefers a flat open dancefloor. As you mention, it's not really built for moviegoers either. But it is still a really impressive and enjoyable experience and I hope they can figure it out.
(And just be clear, my paraphrase that you quoted was referring to the original article)
