Hi-res streaming on Qobuz

Although hi-res titles on Qobuz indicate streaming at 96kHz or192kHz, I’m not sure my system is reproducing those levels. Both my Arcam Rplay streamer and Schiit Gungnir multibit manuals indicate they accept up to 192kHz.  But I can’t hear a difference in quality comparing hi-res to non hi-res files.  Even if I do an A B comparison using the exact same titles with Qobuz hi-res and Idagio CD quality  resolution, I hear no difference. There are no indicators to tell what’s happening, so I’m wondering if I’m indeed hearing in high resolution.
Is there any way I can be sure?
