Prometheus Set & Location Pictures

Alien3 has rose coloured glasses in it's favour.

B and C Deck on the Nostromo are the grubby run down dirty sets.  A Deck - not so much.  Bits look messy because of the way it's dressed with banks of circuitry and stuff but it's not actually dirty per se.

You'd never see a crew member of the Nostromo clean the grime from the walls like you do on Fury 161.  Still, Brett always seemed more disheveled to me than any of the prisoners on Fury 161.
