Bug report: ACM on (SDR) is detected by Go2HDR as HDR being on. (LTSC 24H2)

I use ACM on SDR mode, but Go2HDR believes HDR is on in this case, unnecessarily aattempting to adjusting the SDR slider (probably failing, i do see some vague oddness happening sometimes with adjusting brightness)

I believe it is somehow possible to discern SDR +ACM on, with actual HDR mode. You could approach the GoTweaks dev I believe he was also able to discern the two modes with his software.

Thank you! @Rayekkk

Hey, thanks for the report!

This bug has been fixed in today’s 2.1.2 update. Please test it and let me know if everything is working correctly.

Thank you. I was afraid that if there is no detection happening from SDR(ACM) to HDR, the initial HDR slider calibration also didn't function and was wrong until i manually changed my screen brightness to get Go2HDR to actually do its thing.

Will definitely report back.

The detection seems to work fine. Can you confirm that no WMI command is necessary to slightly change the display brightness for Go2HDR to kick in after HDR is enabled? I was applying this methodology just in case, especially for the reason of ACM/HDR not being detected properly.
