I run my HAP in to a Vinnie Rossi LIO with DAC 2 module and the display always shows the native resolution of the original file (does not show bit depth though). The Sony does not upsample through the USB output ( I wish it would allow the DSD resolution upsampling option through the USB output. This is only available via analogue line outputs).
Something wierd goin' on with your setup.
