Motley combo? Determining morph traits & sex

Hi everyone! It’s my first time posting My brother got me a corn snake which I LOVE, but not knowing much about where to get reptiles, he got it from Petsmart. Of course, they knew nothing about the actual snake they were selling. When I called to ask the morph they said “fancy” and they didn’t know how old or the sex. I’m hoping with the pictures attached I can get some idea of the sex and the possible morph traits. It seems to be a motley but it has a deep maroon red and a very pale beige belly, a combination I haven't seen on normal motley snakes on google. I’m wondering if he could possibly be a mix with ultra, buf or/and kastanie (or something else completely). Any ideas?
