If we're going for a meta explanation, maybe since she hasn't been introduced yet, the artist hasn't been able to make everything around her look like shit yet. It seemed like Rose and Jack both noticed it when they were introduced.

I wonder why Kanaya hasn't noticed anything yet. Sure, she might not have talked to anyone yet, but why hasn't she seen the corruption? It seems fairly noticeable.

I'm kind of hoping that she ends up getting corrupted once she encounters the shittiness. Can you imagine the horror?
