Hololens had 1268x720 per eye[1] or 1.8MP across both eyes. Vision Pro is 23MP across both eyes. Are you seriously saying that's "incrementally better"? It's a literal order of magnitude more pixels!

Then again, sometimes incremental ends up sneaking up on us and being revolutionary in the end. There are many technologies that appeared in the 80s (if not earlier), yet did not turn out to be practical until several decades of incremental development happened.
(That said, the Vision Pro is a bit young to tell how much of an impact it will have.)
In terms of what they do for the user the difference is, in fact, incremental compared to when VHS first became available. VHS enabled you to choose what to watch whenever you wanted. Prior to that, you got whatever was on whatever channels you had access to.
I will definitely grant that enabling subtitles was a profound difference for a subset of viewers (those who enjoy foreign media and the deaf) but even that came about with DVDs, not Blu-ray.
Closed captions were available on many, but not all, VHS tapes. Not all DVDs had subtitles either. The problem with CC on VHS was that it was often the first thing to degrade before the picture and then the sound.
Foreign films often had subtitled releases "baked in" to the video. Here's another hit of nostalgia. There were times you'd walk into a Blockbuster in the USA and the only available version of a hot new release was the Spanish or French subtitled version. You had to deal with the lost sections of image dedicated to subtitles in a language you might not even understand!
Now, you find out about a new technology or product instantly, and you learn about them constantly. It is rare that a company develops something new enough that it's significantly differentiated from something you already know about (or even have) that it's exciting.
Even Apple had a lot of leaks before Vision Pro (which is potentially the most exciting new technology product, at least for me, in years). They had to balance when to announce it with the leaks - to maximize the impact while ensuring you didn't have to wait too long to get one.
