Yeah these labels are fascinating. I studied jazz at a conservatoire and also played in the "classical" Contemporary Music Ensemble which played a lot of this difficult to define art music. And there was the amusing rift between popular, jazz and classical students in terms of what music was about and later working as a session player of sorts I used to laugh (internally) playing jazz sets with some function bands because they didn't play any "actual jazz" and didn't play it "properly" and yet nobody else would even notice. It's fun to debate music and genre definition, genre lacking enough nuance to even work effectively for lots of music. If I recall Soweto Kinch (UK rapper and sax player) had difficulties with record stores putting him in jazz, and ideally he'd wanted to be in urban sections also. For musicians and composers I think genre definition is more of a necessary evil than something helpful.
