You're right, I was wrong.
I'm mainly refering to the "cleaner" environments, in terms of not being as busy as the Nostromo.
& Flatter, less angular surfaces. The vents in Hadley's Hope is a primary example of this.
Perhaps what I should say is that Aliens isn't as visually interesting to me personally as the other two films I mentioned.
But that's maybe just more so JC's shooting than what he shoots.
