I can go with a hard "nope" on all of your opinions and conclusions here dirk.
I have a very specific set of objective physical attributes that I am looking for when analyzing a game.
Videos are extremely useful to my style of objective analysis.
I get about 90% of what I need to know about how a game -- how it sounds and shoots -- from watching an hour of game play.
More often than not, playing in person is a trivial exercise for me, and simply confirms what I determined from the videos.
Now to highlight your general point of view, I can say that it's typical for me to notice something delightfully special about the game in person that I couldn't realize from the videos, but it's typically trivial and subjective compared to the information I can gather from watching videos. Such as (the lighting feels good, or the ramps feel smooth)... Which is small in comparison to: "25% of the bricked shots fly into the outlanes with no recourse possible -- that sure doesn't look like fun design."
I do not expect most enthusiasts to have the same level of obsession with physics, and exploring the sound sets that I have, and thus may not gain the same value from watching ball travel in videos, and listening to the sound (with video off) as I do.
I think more people are excited by theme, code, and LCD integrations.
