Sample rate/bit depth display question

Volumio Information

Volumio Version: 2.873
Hardware: raspberry pi 4
DAC: fiio k5 pro

Just wanted to verify that I can trust the sample rate/bit depth displayed in the volumio playback gui.

I’m playing a .dsf file over the network, and volumio is displaying DSD as expected, buy my Fiio K5 pro is showing LED color yellow, which indicates anything over 48kHz but not DSD, as DSD is indicated by Green LED color. Wondering if it’s possible there is some conversion happening so that my DAC isn’t actually seeing DSD, or maybe just an issue with my DAC?
