I had this exact same problem with my RX460, however this was fixed on 18.3.4, could be they've broken it again.

The thing is I replaced my RX460 with an RX 580 recently so if they have broken it, they may have just broke it on the RX460, all recent driver versions have worked for me, I am currently on 18.8.1

Remove the drivers completely using DDU and reinstall again using 18.3.4, if that works then try 18.8.1.

EDIT - double check again MADVR is set to 10bit, DIRECT3D11 is ticked as well, but also turn on HDR in windows just to see if HDR is triggering at all, but remember to turn it off again as this should always be off.

One other thing that has caused an issue for me is refresh rates, make sure you are playing the video in 23,976, there isnt enough bandwidth for 10bit 60hz 4k playback.
