I have a bunch of 192Khz/24bit FLAC music and I was wondering if my Android TV box was able to output that resolution or if it was limited to a lower one.

The app shows on one of my devices (Formuler GTV) that it supports up to 192Khz sample rate but it appears limited to 16bit, though I'm not sure if it's a limitation of the box:
