I don't know the genetics that make up a phantom as I've never heard of the morph but that just looks like an albino to me. Quite a bit like some of mine that I believe are W/Y Tremper albinos. I'd ask the breeder what the genes are that make up their definition of phantom. I'd love to hear what they say!
If you can ask the breeder for the genetics of your gecko or its parents then we can help you figure it out better. It looks similar to the pictures of a phantom on their site, but it looks like a lot of other morphs also. With out a any genetics we can't give you anything definitive, I'm sorry. [emoji20] Very beautiful gecko, though! [emoji3]
If the parents were both Phantoms then I would say it's safe to say your gecko is a Phantom also. It has the genetics for it.
You see Banded RAPTORs and Banded RADARs that look similar to your gecko. But now that I'm on my computer, and not on my phone, I can see it's eye better and it doesn't have Eclipse eyes. That rules it out as either as either of those morphs. Plus the parents are Phantoms so it doesn't have the genetics to be either.
According to the Urban Gecko, the phantom morph is line bred. Unless your geckos came specifically from phantom lines, it wouldn't be a phantom. That would be something to figure out from the breeder.
If Phantom is linebred, you will see a variety or results. I don't buy into the whole Phantom name thing, but if that's what the parents were considered, then your gecko should be, too. But it all depends on what the parents were.
