Yes, sub-saharan diversity is even more diverse. But diversity among African Americans is still much higher than that of the white population. In fact, most African Americans descended from enslaved have 20-40% European/white DNA (and for unspeakable reasons, most of that DNA is of the supposedly wealthy, elite, most intelligent white progenitors of this country). So I just see no way to make any useful extrapolations based on genetics. Especially considering the externalities involved in being Black in America.

The white admixture could allow you to do admixture studies. Ie examine the inherited white regions see how white polygenic educational attainment scores vs pigmentation scores affect outcomes

This is explicitly forbidden in terms of use of the best databases however
