Using an 8 bit codec with HDR content may affect video quality

I am trying to export HDR for YouTube in Compressor from FCPX 10.4 and I keep getting this warning. "Using an 8 bit codec with HDR content may affect video quality". But it is was shot on Panasonic VLogL at 10bit and was setup in FCPX as wide gamut. Can anyone tell me why I am getting this warning and how to fix it?

iMac (Retina 5K, 27-inch, 2017), macOS High Sierra (10.13.2), 32 Gb Ram, 8 Gb Video

YouTube now supports HDR. I have tried both doing this through the Compressor directly to YouTube and that is where the warning shows and sharing as a master file at ProRes 422HQ which is surely 10 bit. Also the exported file, looks very different from what I see in the viewer of FCPX and I am assuming that is because my iMac is not HDR.
