Apple tv with Apple music hi res streaming issues?

I am trying to get hi res audio from Apple Music and Amazon Music HD through my Apple TV.  But as I understand it (From Apple website) IF I stream through my Apple TV the MAX resolution I can get is 24/48khz which as I understand it is only CD quality.

So, how do I get optimum hi res audio streaming quality then?  Do I try to just go to the Apple Music Apps on my smart TV and not try to stream from my Apple TV?

I have changed the settings on my computer to the hi res settings BUT the Apple forum says ONLY 24/48khz but not 24/192 hi res.  That makes no sense to me.

Please tell me your thoughts.
