Not necessarily true. Back in the day it was hard for some folks to see a difference between Miles and Grand Funk. That link was desired by Miles and Clive Davis and they wanted to exploit it. Some folks are still parsing the details.
Little of this matters. It is about "music"(for me - others have different agendas) and Ms Spalding is making a career by riding on the backs of hundreds of others.
I'm sure she will do well. I hope she does well.
