To the extend that AES is a good random number generator, only if you have a complete dictionary of all blocks. Simply because a random number generator should produce independent output even if you only have a small perturbation in the input. That is, there should be no relation between a completely white block and an one where one of the pixels has a value of 0xfffeff.
