Is using streaming services worthy of an audiophile?

Yes, yes, and no. 

@douglas_schroeder 

Could you be a bit more specific, please. 

Specifically, how do you know that the claimed file quality is actually streamed? What prevents streaming services from downgrading their signals?

Tidal good
Splatify bad

Many DACs will give an accurate read on what bit Rate, etc is actually arriving at the DAC.  Many on this forum have used this info to discover that some streamed music from Tidal or other streamed sources is not high res, and occasionally discovered that MP3 files are being used
   Tidal tries to minimize this, but to answer your original question, the only way to control this is to own the file in a physical format
