Is Apple Music lossless/uncompressed?

I gave up following what the hell Apple was doing with music long ago cause it’s just been a confusing and disappointing mess, but a friend is considering using Apple Music and asked me if it’s lossless so thought I’d ask here to hopefully get the latest poop.  I thought I recently read they were introducing some new lossless format but I dunno about resolution or what it might cost?  Also, how does the music selection/resolution compare to Qobuz or Tidal, and does Apple Music offer hi res?  My friend is planning on using the Lightning connection from his iPhone to an AQ Dragonfly Cobalt in case that’s important.  Thanks for any thoughts/info.
