I think the one you'd have to ask is Bob Clark. Look up Bob Clark Reptiles and email him for clarification. He's been breeding all the different burm morphs for a long time.
These are photos of some of Bobs blondes..
While I'm no burm morph expert, I'd say no considering how dark it is.
Those are Bob Clarks photos and they are marked as Blondes. That's why I said you should ask him. Try to get a picture of it in daylight or under a daylight bulb with a real camera.
As far as I know, both Burmese pythons and Sri Lankan pythons are Python molurus but aside from that I have no idea what the differences are really between them. However I second that I think you got took, that looks like a slightly lighter normal, but not a blonde to me.
