The only thing you need to see is how many Apple employees use them. Answer, almost none

If it was amazing as a display for work then most Apple employees would be using them at work. It's not, so they aren't

If it was amazing as a movie viewer most Apple employees would be watching movies on them. It's not, so they aren't

repeat for any other use case.

Compare to iPhone/iPad/Mac, every Apple employee uses them. Probably included in that Airpods, Homepods, AppleTV, Apple Watch.
