No, I wouldn't expect this at all as I do not expect the height distribution of basketball player to reflect the height distribution of the general population. As I do not expect the personality trait distribution of pop stars to be the same of programmers, and again I do not expect the latter to be similar to the general population. Personal inclination, innate intelligence, talent, conscientiousness, and of course demographics, parenting, generational wealth all play a role.
Skin color is not an advantage when programming. It is also a characteristic by which it is illegal to hire a programmer.
That can be measured (imperfectly, but well enough), by filtering only for qualified candidates and then comparing the rate at which both A and B are hired and the rate at which they appear in the filtered list. E: This of course requires the filtering to be done _only_ with knowledge of a candidates skills/accomplishments, and association with demographics (including name, location, etc.) to be done only after the sorting.
If it doesn't, you have an issue. The only way to know for sure is to measure.
E: To be clear, assuming equally qualified candidates, you would want expect hiring proportions to match the same A:B ratio as you get from applications.
