Yes, it does talk about similar notions, and I think I remember it using the specific words "illusion of change" and "window dressing" when describing how serial format comics stay generally in the same place and the characters are static, even though it
seems like there's evolution and growth because details and supporting characters change over the years.
I think the author even said that Superman and Spider-Man getting married is only "window dressing," although for Spider-Man I'm not sure I agree. Superman represents "traditional values" (but not those of fundamentalist bigots, etc., since he doesn't support prejudice, disenfranchisement or oppression, from what I understand), so him getting married is just the next step up from flirting with Lois for 50 or so years. Spider-Man, however, while still representing the same values that Superman does, did not come from a nuclear family (yes, Superman's adopted family was nuclear, and since he never knew his birth parents, they're the ones that count) and is not as "well-adjusted" as Superman, and was generally seen as more iconoclastic. He was a lot more self-centered, neurotic and witty than Superman. I'm not saying he didn't care for others, but he had a hell of a lot more personal problems to worry about than Superman. This is why it seems that more people in this generation are interested in Spider-Man than Superman, and I'm one of those people, even though I will always love Superman as he was the one who got me into superheroes for life.
Anyway, I think it changes things for Spider-Man to get married, while Superman carried on mostly the same as always, while having to make less excuses for his unpredictable comings and goings.
You should check that book out, although I can't say whether it would tell you anything you don't already know. You've obviously got a good understanding of this stuff.
