Something tells me Daedra would seem far more alien if brought into an incredibly contrasting alien environment than in normal everyday forests. The reason people in Morrowind have that reaction, is that the alien Daedra are in a not-so-much contrasting ash environment. Whereas Cyrodiil's alien (for most of us, at least) jungles would contrast even more to the Daedra.

(NOTE: Of course, this is all personal taste, so don't take my post too seriously please.)
