Is he really a granite ball python??

The seller told me that he is a genetic granite ball python, but i can't see the different between this boy and normal ball python. please, tell me whether he really is a granite ball python or not? Is he really this morph? thanks a lot :D

The black dots on his saddles are granite signs. Looks like it to me

He has the black dots characteristic in Granite.

he does resemble a granite but some granites are not genetic...you would have to breed him to find out...I have a granite like female I picked up but not saying shes a granite till I breed her and it proves out...but one of the signs is a clean belly...there are other traits but I forgot them.lol

many thanks :)

Is the breeder someone reputable? Looks of normals can look like granites.
