Hi Everyone!

Long time lurker, first time poster. I have somewhat of a stupid question but I searched the interwebs and came up empty. I recently acquired a 6 year old albino python that while although not neglected, she could have had better conditions. The person I got her from had in turn gotten her from someone else recently. This is where the problem arises. This girl is big, she is about 5.5 ft long. When I got her he said "I am not sure if it's a ball python or a burmese python" (this guy was definitely in over his head and didn't know much about snakes). My question is, are there any visible differences between a burmese and a ball python (aside from the size). Could it possibly be a very underfed burmese or just a big BP girl? Here are a couple of pics. She is not too happy right now and will not cooperate for pics. I have yet to see her curl up like my other balls but I am not sure if that is indicative of anything.
