Question on my DAC


I have an ARC LS27 preamp and recently bought a used Bryston BDA-2 DAC which improved sound quality significantly. Oh so satisfying...
However, I have a question about sampling rates: I stream music from Deezer and the new Amazon HD streaming service. It seems no matter what I stream, including remastered recordings etc, the sampling rate stays at 44.1Khz. There is also an LED that indicates it's "locked".  I can push a separate "upsampling" button, but the lock remains in place and also stays at 44.1KHZ. I don't see any "unlock" buttons and the user manual doesn't give a lot of information on that subject.  My source is a Bluesound vault and I use the coax output.
Again, I love the sound this thing produces so I'm not searching for better quality, just curious about how the sampling is supposed to work.
Thanks!

I finally got it to sample at 96KHZ after I found a "legacy" recording in Amazon. I wish these streaming services would be clearer on what exactly the sampling rate was. It doesn't appear there are many recordings above the 44.1 KHZ level. Comes across to me as misleading. 
When I go to Amazon HD or Deezer, I see no indication as to what the sound quality should be. Is there a way to identify this on their app.?
Thank you!
