That would be cool if they do see him differently. I would like to see through their eyes how Grimms appear. Much like how we saw Adalind "see" the scents. But I think that the creatures are very sensitive to human body language and notice the look in Nick's eyes and/or the reaction in his face, when he notices they have let down their "guard" for a few seconds to reveal who and what they really are.
