Verify colors using ONLY calibration

[Mionwang]

I want to verify the colors (using any of the large video test charts) of my display with ONLY the 1D VCGT applied system wide, and without taking into account the display profle (ICC/ICM). Is there a way to do it?

Evaluating grey balance through calibration alone only applies to the grey balance and the rest of the colors don’t seem to get affected by that. From what i can tell, using absolute values and display profile white point as reference still takes into account the ICC profile and corrects the responses.

Any help would be really appreciated. Thanks

Option A) HCFR, make sure to do not disable VCGT loading, it bat be dest to disable by default.
Not as detailed as DisplayCAL report.

Option B) Use DisplayCAL on a virtual machine.
On  host (real PC) you load VCGT in displaycal tray profile settings (if MS Windows)
On guest (VM) run displaycal and verify. You can
B.1) set as VMs display profile the one you want to verify
B2.) use “simulation profile “+ “use simulation profile as display profile” on the prpfile you want to verify against. If applied on a real PC it will clean VCGT 1D cal, but since it’s a VM it wont do that since it has no access to host GPU.

The functionally you ask is not fully supported in DIsplaYCAL, more oriented to ICC color managed apps although it can test what you ask on HW cal using “B2” on a real computer.
I’ll go for B2
