That's not true. It's an Android issue as Android SRC limits all output systemwide.
To have anything higher you need an app like USB Audio Player Pro that bypasses the SRC and an external DAC.
Is usb audio player does it, can't Amazon do it? Or is it not that simple? Edit my bad, nevermind. I see the need for the dac.
In this case the post metioned the LG V30, which has a high-end internal Quad DAC. The Tidal app bypasses the Android system to make use of that DAC for MQA, and UAPP does the same for all streams from Tidal and Qobuz.
