This has been puzzling me a bit ... it's not a scale with which I'm familiar, but I would have considered it to contain the natural fourth and the flat fifth, not the sharp 4th, so G, A, B, C, Db, E, F#.
My personal view is that it's not a Lydian variant, which contains the sharp 4th, not the natural fourth.

I'm no expert, though, so maybe AI outranks me here?
