In the profiling subsystem there is a tab called manual measure that has sliders to select the patch color and measurement results. In the results section there is a 3x3 table which has Y x y rows and Target Actual Deviation columns. It would be helpful if there was a version of the table with R G B rows instead.
That is actually impossible. RGB values are not measured by the probe; they are input patch stimulus values only.
And unfortunately, putting up a black patch will cause as much 'change' in the screen as any other patch - just differently.
The display will cool for example, and that will cause as much change as anything else.
I do understand where the request is coming from, but it's not actually the real answer.
I guess ideally, running a fast - full screen - patch set, with varying patch colours, is likely the best idea...
But that's not something that can't be added easily/quickly.
I will add the idea to the WIBNI list!
