Hey all, I’m calibrating a Macbook Pro display and I can’t really nail the whitepoint/ whitelevel (first part of the Interactive display adjustment) as the built-in display offers no external control over rgb gain/ offset. See the attachment.
This deviation is fine and compensated for in the generated .icc profile?
Last, the calibration process ignores the active .icc profile when a new measurement is taken?
(Guess so :-))
White is another grey, so it will be corrected in GPU although you loose a few unique grey levels, max brightness and a little contrast.
If you had one of those new miniLED macbookpro with XDR screen you should use built-in Apple app to provide “HW-like whitepoint caibration”:
-measure native whitepoint with DisplayCAL (use macbook WLED PFS correction fro i1d3 colorimeters)
-copy measured coordinates to Apple app for customization of XDR presets & set desired whitepoint.
And that’s all, then you can validate results with DisplayCAL.
