NPR Audio Quality and Upconversion

NPR posted an article questioning whether listeners can discern the difference in audio formats, and subsequently if services such as Tidal are worth the money.

I ran through the six tests and to my chagrin I only got three right, and those three were not confident selections. I checked the settings on my DAC and realized all the tracks were registering as 192khz, and I have up-sampling turned off.

After I upgraded to Windows 10 this weekend for some reason the driver settings changed and the DAC was set in Windows to play at 192, not 44.1 where I normally keep it for browser streaming. After changing it back and trying the test again I got all six correct and the differences between tracks were blatant, it wasn't a challenge to pick out the uncompressed file.

So is this a knock on up-sampling or is there something else going on?

Second question, is there a way to set Windows to dynamically adjust the DAC output setting when streaming via a browser? Running Tidal in Chrome my DAC (Teac UD-501) only sees whatever sample rate is set for the device in Windows. In contrast, it sees whatever type is fed to it via JRiver.
