What he is right now is pretty meaningless - what he'll be in 6 months is the real deciding point. I'm guessing that his mask won't change significantly, but it might.
Your puppy is still way too young and coat colour and markings in general will gradually change until he's 6 months - a year old. Not meaning to sound off, but stick around and we'll be glad to tell you in a while.
