Of course, if you know you have a seer in your party, you can plan ahead and come up with some prepared scenes. They don’t neccesarily have to be predicated on what’s going on near the players either; they could, for example, foresee the bbeg tormenting his captives - get some flavor about how evil he is, maybe some plot-relevant information to use later, but it doesn’t actually depend on which level of the dungeon they’re on or whatever. Obviously, this depends on the details of exactly what spells they’re using and in what system.
