IFI STREAM music

I just bought the Ifi Stream and using with Denafrips Ares ii and subscribe on Tidal MQA. My question is I only get green light on the Ifi Steam and on my Dac reading either 48k or 96k even im playing 192k. So what’s going on on my Ifi Stream? Saying it will change the color depending on the music resolution. Can someone can explain to me what’s going on this Ifi Stream?
