Also, intellectual types tend to be more story oriented and certainly cafe society types want to have us believe they are "above fluff" and only care about content (whether actually true or not). People talk about "their experience" but that is always, inevitably, just the people they know, who are not representative of the general audience. I could just a fallaciously say that in my experience the average person crosses the Atlantic by plane 3-4 times a year - even though that's nonsense even in a rich country - because that's what I see amongst most of the people I know.
Again, proof of everything I state here is in the $$$ studios spend on extraordinary visual quality. You think they threw in all those minutes of Imax in Dark Knight because they are passionate about art, even if their research shows audiences dont care? If you say that you have never actually met a studio executive (my guess is you have, and need only think about this for a second).
There is also the matter of making stars look good. I have many times saved a shoot by being ruined by DSLR usage, back when that was "the in thing", by showing what the line-skipping did to accentuate women's pores and thicken their eyebrows - in side by side tests. The actress/model/singer would then invariably refuse to be shot on that "garbage". All this to say it's not just the audience, it's the talent too.
That said, I look forward to testing your new plasma lights. They seem to be great new tech which meet our extremely stringent standards of visual perfectionism.
