I have 2 ghosts and purchased both at under 200 grams.. Both were light and faded when I got them. He could be het for it, but unless he was sold to you as that, I would not bet on it. Orange Dream usually reduces / cleans up pattern, but I'm not sure if one can have the busy patterning like your guy.

Maybe yellowbelly?

Desert ghost can have very dark blacks and clean yellows and keep them their whole life, but if you had purchased a desert ghost, I think you'd know, as they run a lot more money than OG or OD combus usually... around $450 for a plain DG and more for any added genes.

Maybe check with the breeder and confirm. I could maybe see DG, but again, not sure unless you know the genetics.
