Strangely, although the Flex manual says digital outs are 48 kHz with DIRAC?DDRC24 plugin, I am reporting 96kHz with two different DACs (RME ADI2- pro and Topping E30). What is actually happening? I haven't run a 96kHz sweep through it to confirm whether it is downsampling then upsampling, but I guess I could.

Yep, I did a 192kHz sweep using the USB input, looping back the dig output via USB.  BW limited to 24kHz so must downsample to 48kHz in DIRAC part then upsample again to 96 kHz in the output module. DAC still reporting 96kHz.

That would make sense, but just to be sure were your computer audio input and output sample rates definitely set high enough that they weren't influencing results? Just asking as I know it's easy to miss this.
