Nah that's just Tidals marketing talking. "Anyone" can submit music to Tidal through services like DistroKid etc. However, to get the Tidal "MASTER" badge on your song, you basically just have to pay them extra. I don't need to submit another file to them, so it's the same master. It might be that they do some post-processing on it, but it's not the revolutionary thing they make it out to be.
