I can certainly tell you that a kitten who is on a raw/quality canned diet WILL develop more muscle mass than a kitten on kibble or low quality food. That in itself is proof that meat protein is so important in the development of the kitten.
You could always ask your vet where in a carnivore's diet corn/wheat gluten fits in?
