Yeah, absolutely. It also shows though how you can easily accidentally bias a blind test. If an artist did manage to create a perfectly realistic render but forgot to add in one of the subtle unrealistic effects that cameras cause, people would be able to tell which images were photos. (Although, maybe you could argue that if the challenge is to make photorealistic renders rather than realistic renders, nailing the camera artifacts is part of the challenge.)
