MHC2: Still can’t see “Automatically manage color for apps” in the setting

Tried appending the item in registry like blew and rebooted windows.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]
"EnableAcmSupportDeveloperPreview"=dword:00000001

Still can’t see “Automatically manage color for apps” in the setting.

While I am using it in its SDR mode.

Edit your monitor’s EDID with CRU by un-ticking colorspaces checkboxes in CTA-861 extension block -> Colorimetry: https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU

Then HDR should become unavailable, which makes the clamp toggle appear.

Your display seems to be HDR-capable: https://www.lg.com/us/monitors/lg-34WK95U-W-ultrawide-monitor

SDR Advanced Color is currently unavailable on HDR-capable display, nothing can do on my side.
