Jeff Davis said it himself, True Alphas don't have special abilities that can only be acquired by them. True Alphas are just like any other alpha werewolf, except for the fact that they didn't have to steal their alpha status and only a Beta of their making can steal their alpha spark.

Scott's fangs being different, relates to alphas in general, not just True Alphas. Peter's fangs were different as an alpha as well. Liam even says that Scott's fangs could be different bc he's an alpha and he's becoming more of a werewolf. Its also been established that all alphas have that more monstrous shift, once again, this applies to all alphas.
