No your ignoring everyone else who sited other Hale's in their Alpha form.

Now I agree that perhaps the production team used more CGI in the beginning to differentiate between Alpha's and Beta's and then dialed it back to give the characters a more human and therefore more sympathetic look.

I also have another theory though. When looking at the Alpha's Deucalion's Alpha form looked most like Peter's and Kali's form always had the animalistic feet. One might deduce that the Alpha form gets corrupted, perverted the more a Alpha kills, becoming more monster than wolf or man.

Of the Alpha pack the most powerful were Deucalion and Kali, we can assume this is because they killed more of their kind then the other Alpha's. Their Alpha forms therefore where more monstrous like Peters. Deucalion killed the most of his kind and therefore was the most powerful and more powerful than Peter's Alpha form due to him killing werewolves. While I believe Peter killed many innocent people probably more human then werewolf and may have even had a hand in his own families demise(he said as much many times to Derek, Stiles and Sott that his eyes where blue many times over). As such the more they killed the more perverted their Alpha form became.

We might also assume this hypothesis due to Derek's mother and sister who where described as extremely pure and had the ability to become full wolf and human, suggesting they found balance in their forms, futher supporting this hypothesis of Alpha form perversion being due to a Alpha being evil.
