Unless someone has knowledge of the inner workings of admissions offices, I think the most honest answer is we don’t know. Selective schools still value diversity in all forms and they’ll look to meet their targets in a way that don’t run afoul of the law. But we’re don’t know how they’ll do it and whether they will have adapted to the situation by this fall or not.
My advice is to simply present your best self and not worry much about how this ruling may or may not help you.
