Do the servants in Amnesia actually look like that or is it Daniel's sanity?

I think they really look like that, when you read about Wilhelm and his men it talks about how they appear to be changing after drinking the wine. And for the servants sulking I just assumed that's all Daniel could see was the outline of them where they appear to be sulking, due to the fact that it was kept dark in the castle.
