Then optionally it can store grey calibration (and white is a grey) in VCGT tag. That’s DisplayCAL or i1Profiler grey calibration stored inside ICC profile.
The gray calibration & white are stored inside an ICC profile only when using DisplayCAL and a i1 Profiler ?
No, with other GPU Calibration software will happen the same. For example Basiccolor if your computer has no support for HW calibration with it, or i1Studio software.
Profiling software (with GPU/HW cal… or whatever)=> create profile that describes display
GPU calibration software => also includes in VCGT tag inside profile white & grey calibration
I don’t follow ?
