We tested a calibration using i1Profiler / ccProfiler and the resulting profile is closer to sRGB than P3, no matter the preset, which is strange. He’s having a bit of trouble with Argyll on the latest MacOS Monterrey and Apple Silicon chip so we couldn’t test a raw output using dispwin, but it seems that the presets actually change the output downstream, on the GPU path, as Vincent suggested. Even if selecting sRGB, the profile still informs a P3 wide gamut. Just tested it with another user and it seems that the default profile doesn’t change in any way with the presets. I’ll report back here with any new information. The file will be located under /Library/ColorSync/Profiles/Displays/ and the filename will be similar to Color LCD-17D8112G-2A64-01CC-B3F2-8F30Z101B230.icc The best way to test is to select any of the P3 presets, copy the ICC profile, change the preset to sRGB and make another copy. The file name seems to remain the same, but I’d like to know if there are any internal changes to it. Of course, take my comments with a grain of salt since I don’t have the machine here and I’m relying in other people to test.īy the way, if you have a few minutes and would like to contribute, there’s one question still open here on my list: does changing the preset also change the canned ICC profile for the display in any way? It changes the response, so we know the profile is being applied, and also survives reboots and passes a verification report. Using the Colorsync Utility to assign the profile seems to work fine. So did you figure something out how to add your custom ICC?
