is dipsy a winter white/hybrid?

[1tigger7]

hi everyone. i got dipsy my gorgeous hamster from my local pet shop aged 12 weeks on 9th june. he'd had an abcess on his leg which the vet had been treating him for and was up for "adoption" as they said he was too old to sell. i fell in love with him. when i first got him he had red eyes and was white with just a tiny bit of a darker colour on the top of his head and running in a thin line down his back as you can see in the photo. now although he still has his red eyes the darker colour is spreading all over his body. i couldn't upload another photo for some reason so i'll try on another post. what do you all think? winter white or hybrid maybe? would appreciate your thoughts. thank you
