I think you're being a little too charitable to the AI in this case.

Even without "famous person bias", it's fair to say that the skin tone of the resolved image is slightly but measurably lighter than the skin tone of the blurred original (I'm curious what the blurred version of the resolved image looks like, btw).

Occam's razor says the model simply wasn't trained with enough ethnically diverse images, for whatever reason.
