Stellar gain cell DAC sample rate

I have a Bryston BDP-1 connected via spdif into the Stellar Gain Cell, just played an album which is exporting at 24/96 according to the BDP-1 but the SGC is only displaying 16/44.
Am I missing something?

Have you tried with other files?

No, I only have the one album in hi-rez, strangely when I played the album through my bluesound Node 2 the SGC recognised the file correctly. A bit odd, it could be the Bryston that’s the issue but since that exports the raw file to the SGC I am scratching my head. It’s a bit academic to a degree as the pair make good music.
