Color picker wrong results when picking from non-sRGB image using "Sample Average"
Here's a screenshot showing Sample Points and Color Picker Information for an image in the linear gamma Rec.2020 color space. If it matters, this image was a 32f tiff opened from disk, already in the linear gamma Rec.2020 color space, with an embedded ICC profile. I color-picked with "Sample average" unchecked, and the Sample Points and Color Picker Information LCh values do agree (and are correct, in case anyone might be wondering):
Here's a screenshot of the same image, still showing Sample Points and Color Picker Information, this time with "Sample average" checked. The Sample Points and Color Picker Information LCh values do not agree. The Sample Points LCh values are correct and the Color Picker Information values are wrong:
If it matters, this image was a 32f tiff opened from disk, already in the linear gamma Rec.2020 color space, with an embedded ICC profile. Here's a crop from the image, exported as a 16-bit png and showing the cyan color patch:
I only checked linear gamma color spaces, didn't try any image with an embedded ICC profile that didn't have a linear TRC, in fact only tried a linear gamma Rec.2020 image, but that should be representative.
