firstly, the background to your website is ridiculous, please have it stay one colorits painful to view.
secondly, generally if you have to ask "is my bp a morph" -- it isn't. You pay more for morphs because they are different. did you purchase your ball as a normal? if so, most likely it is a normal. Sure there are dinkers and new and different morphs coming out occasionally but if you think you have something truly genetically different from a normal the only way to tell is proving it out by breeding to see if the look is inheritable.
Off the top of my head i can't recall a single morph that is classified by belly pattern alone. Yellowbellies have a specific belly and body pattern, etc.
So, in a nut shell i'd say no it isn't a morph.
