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!

MQA will give you 96
That’s what it does on my BDA-1
I’ve gotten 192 on Qobuz
A lot of stuff that says HR on Qobuz locks at 44
Regular files also lock at 44
The HI Res may be 24bit instead of 16, I have no way of telling
Qobuz will do 24/192
Deezer is 16bit FLAC. Have no idea about Amazon
I wish Amazon would mark the files. There is no indication of the sample rate
I’ve never seen anything above 44 on Deezer, but I’ve only had it a short while
Just my brief observation, only had the DAC a week or so
Up sampling does not change the sampling rate on the front of the DAC
The manual has the up sampling info
