"Demon Wolf" is not a thing. It's a nickname that both Deuc and Sebastien used. That's all. Jeff told us as much, during Paul's end of season 5 interview.

Sebastien was the way he was because the form you take reflects the person you are. Sebastien was a murderer before becoming a werewolf. When he became a werewolf, his form reflected that he was such an evil assbag.

The Fresco also showed the hellhound as a white flame-beast, and the actual hellhound is ashen with lava/fire lines on him. The Fresco's eye colour didn't really mean anything compared to what we got.
