For my laptop, sometimes the calibration is not helpfull since it also lower the maximum brightness of the screen, so i want an easy mode to just switch it off, but I can not find how. On the internet some coments speaks about deactivate the service, but that sounds a bit too “brutal”. OR maybe there is a way i can create a profile witth 0 correction? since changing profiles doesnt seems to be a problem.
How much brightness does it lower? Getting native gamma to display Cal gamma eliminates this.
You can right click on the profile loader and check reset video card gamma. This sets the 1d lut to linear which is native.
You can run calibartion as measured to get native brightness and gamma and get a color profile that is calibrated.
Windows 11 is a problem with displaycal in my opinion. Windows 11 gets the trc right for my tv and displaycal sets it to standard. It sets trc to 254.97 maximum rgb. It stops the red clipping displaycal has. 255, 255, 255 is usualy not a problem on other displays.
Which windows and which display is information needed for exact help. I am just guessing with different hardware.

Check “calibration curves” on profile info of your current custom made profile. Likely that you forced some whitepoint correction on it… but your screen shoudl be very bad behaved to have such big impact in overall brightness.
How much? Did you measure? tools / report / repot on calibrated screen, then repot on uncalibrated screen. Almost the same test but uncalibrated resets VCGT.
