Are you beating them by grinding them into the ground with a strong top game and strength like a wrestler? Then no you shouldn't be a bluebelt. Do you win by submitting them? What submissions? Are you CHALLENGING them? Or are you just asking for a roll where the bluebelts aren't really that into proving their "amazing" skill against a good wrestler whitebelt?
When you use BJJ to beat other BJJ'ers of similar skill consistently. Not only in submitting them but showing strong dominance and versatility of technique and strategy of BJJ , you will be awarded your next rank in BJJ depending on how heavily your instructor values the different qualities that make that rank. The quality that is usually valued above all else in BJJ is technique. And unless you are beating BJJ'ers with BJJ, like I said, there is no reason for you to be a bluebelt, since a boxer can knock out a bluebelt but won't be awarded a bluebelt himself either.
Even Judo and BJJ are so incredibly similar as grappling arts (indeed sharing the same source) to such an extent that it's almost ridiculous. But they are valued as being different enough that your general skill at grappling does not constitute your beltrank.
Your rank is not your pure grappling skill, but your skill in Brazilian Jiu-Jitsu techniques and methods, combined with the amount of training and effort you put into learning it and the time spent doing that. All of that is sent through the scrutiny of your instructor who judges your performance based on much more than grinding some bluebelts on open mat.
At least that's how I understand it.
