Yes, did check of course.did you check your display name in the top under system -> displays ? does it mention hdr in the title? i'm using a lg 4k hdr 27inch monitor with display port running from monitor to my vega frontier edition gpu. did you successfully install 10.15.4 without any errors or errors that mention "bless" before restart? apple announced it will be available to certain monitors that support hdr in the 10.15.4 release notes.
I've now returned this expensive HDMI fibre optic cable (18Gbps) and purchased an HDMI copper with better speeds (48Gbps) to see if it helps.
On Windows 10 X64 & 4K HDR games, I was only getting 2160x3840 @ 30 Hz (10/12bit) HDR on my television, not 60Hz...
I'll do my investigation and report back with any advances on it!
