Could be that the graphics card is outputting an HDR signal (Rec. 2020 color space), but the monitor is in SDR mode. That would result in desaturated colors.
I wish it were that simple, but no. The monitor enables HDR automatically when being fed an HDR signal. I can confirm that HDR is enabled on both ends and it still ends up washed out, whereas before it was perfectly fine. :(
