Store bought gecko

Hi, I normally don't buy leos from pet stores but this one was at a local store for a couple of months and I really liked the way he looked so I bought him... Unfortunately he was already a few months old and I have no idea if he is just a normal leo. I have heard that some Snows can look like normals, even though all of mine have alot more purple and pastel looks to them... Let me know what you all think.

Really can't tell a snow from a normal unless you know what it looked like as a hatchling
