Has anyone ever looked into having oiiotool compute a more accurate color difference (https://en.wikipedia.org/wiki/Color_difference)? For instance, the CIEDE2000. This could help when comparing two images where you only want the diff to fail when the two images are perceptually different. In other words, if my eyes can't see the difference, I don't want to be informed of a failure.
Right now, I can get two pixels with the same error difference and yet one pixel will clearly look different between the two images while with the other pixel I can't see a single difference on my monitor. This means I either have to set my fail thresholds really low and accept getting a bunch of images for which I can't tell the difference, or I set the thresholds higher, but risk being uninformed of visible image differences.
