Most music players for Android use a very basic approach based mostly on the standard APIs. So while they may look different, the underlying structure and library is fundamentally the same and limited to the "standard" tags that the base Android player uses.
There are some that offer better audio engines, and independent library management. But I am not aware of any that will add custom tags like "Display Artist" to their internal database.
Neutron has a great engine but basic library management.
Poweramp has a decent engine and does allow for multiple Artists and Genres. But again no custom tags.
GoneMAD has some extended tag support including the sort versions for Artist, Album, Albumartist, and Composer. Playback engine is limited to 48kHz standard though.
There are others, but none that I have tried over the last decade plus that offer what you seek for the Display Artist tag support.
