From a real life point of view, probably is just a graphic choice, since the "base" warewolf form may look more realistic.

From the show point of view, well we know that warewolfes have at least 4 different forms: Base form: The one everyone can achieve.

Full Wolf: Both alphas and betas can achieve that but is implied that you have to be "special" somehow.

Peter's Form: Only alphas? So maybe that's why Peter no longer use it?

Alpha God: You have to be the alpha of the alphas.

So with that said, we already know that Peter is an expert of the warewolfes abilities, so he maybe he just knew how to use that form. So i think is something like the wolf form, with the difference you have to be an alpha to use it.
