PG34WCDM HDR mode seems have bugs

after I enable HDR in windows the color are way off and overexposed

I need enable bright adjust and set to 100% to get it back to normal

I contact ASUS support (Taiwan) and they ask me to send the monitor back for firmware update,

I don't want send the monitor back just for firmware update .. and I throw the box away already

cloud ASUS just give us firmware update tool for this?

Having the same issue here. Even in 100% brightness the colors look a bit washed out. I can tell since I also have a WOLED TV that I regularly game on.

Use windows built-in HDR windows hdr color calibration tool, set last chroma option to about 30% to solve the washout issue, that's on Windows

 

But the firmware issues need you send monitor back to asus is not acceptable

If so, please provide separate videos showing the issue in each mode. 
We will gather this information and forward it to our backend team for further investigation.
