HDR Support on UHD 630 under MacOS via Thunderbolt/DP?

Hi all, I'm trying to enable HDR using the 630 in my mac mini (2018). As this one only has HDMI and Thunderbolt/USB-C Connections, I'm using a USB-C-to-Displayport cable. The vendor of the cable explicitly mentions DP1.4 and HDR (HBR3) support, and my (main) Display is HDR600 certified. FWIW, a second (non-HDR) Display is connected, again with a USB-C-to-DP cable. Both Displays are running 4K@60Hz. I've initially suspected a bandwith limitation of the iGPU, but disconnecting the second display makes no difference. Per Apple's Documentation, this Mac should be able to support HDR. Using a different Mac (M1), and using Windows (through native DP), I was able to run the Display in HDR mode. Is this perhaps a driver or firmware issue?

Aw shucks, but thank you anyway for taking the time to respond. Let's see if their support is as good as these forums here. 🙂
