I think that's true. The 1780 stuff can usually be dismissed as being something that no-one seriously believes any more. The 1980 one can't.
It's not just the cultural stuff, though. I read Dream Park and the Barsoon Project when I was a kid. Loved them to bits. Recently I found a copy of The Voodoo Game in a second hand book store and finally finished the trilogy. Don't get me wrong, I enjoyed it, but it was like watching an original series BSG episode and expecting it to be as good as... modern BSG.
