17.4 Cannot turn on HDR on M1 Mac

I use a Mac M1 with HDMI directly connected to LG CX.
Using the same settings, 17.3.2 can easily watch HDR.
After upgrading to 17.4, the exact same color management settings and other settings were tried, but HDR could not be activated. After downgrading to 17.3.2, without making any changes, it directly shows HDR......
Do I need any new settings to see HDR on the monitor?
Intel’s Mac has not yet tried

Hi,

This is compatibility issue with 17.4 unfortunately, and we are investigating. For now, we recommend going back to 17.3.2 to get back the HDR functionality.
