One of the things I often see in real application demos that I don't see in fake kung fu demos are smiles of amazement and laughter. Maybe it's me or maybe it's something cultural or maybe I'm just projecting my own experiences. But when I see students smile and laugh in amazement this way, I always think and "know" that there is something real about the technique and about what the person is experiencing.
I've yet to see anyone fake this smile or laughter because it often has an innocent childlike appearance to it. It reminds me of how I've smiled and how I've seen students smile when they have honestly experienced something. It never looks over dramatic. The reaction looks natural and it's not just one sided either. That same happy reaction often shows up on the teacher's face as well. The teacher smiles and laughs as well as if the 2 are good friends. It never takes on that "magical look"
