Bill and Michael are on both those lists, but you would not say they are "black" names.
The thing is, there aren't a large group of upper class black people with different names from upper class white people, so you don't have an image in your mind of high-end black names. The rich and famous black people you know have either normal "white" names or very rare names (Beyonce, Prince, Tiger). High-end names default to looking white, since white is "normal" in USA.
Don't forget also that for many of those black names, those people are celebrities and sports stars: they don't have to worry about getting a job interview at some soulless corporation. Beyonce, Oprah, Shaquille, etc. made their millions in the entertainment business and likely never had to deal with that. However, someone sending in a resume with the name "Shaquille" for a programming job isn't going to get a pass just because he shares a name with a basketball legend; he'll be subject to whatever bias about black people the resume screener has.
Oprah, Michael, Tiger, Sean, Robert, Mariah, Earvin, Jay, Bill, Sheila, Tyler, Shaquille, Dr, Master, Berry, Russell, Quintin, Beyonce, Prince.
