As I told you in the other thread, contact Ozzy and ask him to ID the snake in your pictures because he started the OD project and he's the resident expert. All we can offer you is best practices and our opinion, which is impacted by photo lighting, the source of the ball python being sold, price, etc.
Here's what I saw, so it can be proven or disproven for you by an expert: To me, it looks like an OD because it's got the creamy coloring and almost-enchi-like fade along its sides, as well as the heavy orange flames. It also has the reduced pattern that looks similar to the OD in the video I linked. That said, the others who replied are correct - it could very well be a normal that has similar qualities, and the gene is already hard to differentiate from wild caughts. I could very well be totally wrong about what I see. Some people have said the belly has similar markers as some het. pieds, while in the video I linked he says the belly is unremarkable and there are no markers. That means people can't even agree on markers yet. It's ultimately up to you if you want to gamble with your money and time on this snake. But getting info directly from the source of the gene is the best chance you have.
