You're conspicuously ignoring the initial point I made in my post, that being a URM is valued more highly than being an "exceptional talent" at a number of elite Universities. And at those where it's not the most important factor, it's very likely one of the most important factors.

Test scores are just used as a proxy for overall application quality. If you are a URM, it's much easier to get into elite colleges.
