What counts is the releases, not really what’s online, as much.
Mixture of spelling on artist page, as long as they all follow what is printed, is totally ok.
It’s only ugly for you if you (want to) see it ugly. 
I think we should not change a release style because of other releases.
And it seems that the other release groups are already in This Style as Well, anyway, no?
