> I remember the days people compared their colorimeters and profiled their own monitors. That would be calibration and it's still necessary if you want color accuracy. That's about ensuring that what your monitor thinks it's displaying and what it's actually physically emitting are the same. The main thing that's changed here is that factory calibration has become a lot more common and is often more than good enough for anything short of serious professional work. Even for things that aren't professional displays. Like most flagship or even midrange smartphones are factory calibrated with dE values that would make reference monitors from 20 years ago blush. Right up until the OEM shoves a shitty color curve on it intentionally to make it "pop" or be more "vibrant" (Samsung calls this "Vivid", Pixel calls it "Adaptive", etc.. - but they at least usually have a "natural" option that gets you back to the properly calibrated display)

> That would be calibration and it's still necessary if you want color accuracy. Your correction is backwards. Profiling + colour-managed apps gets you accurate colours regardless of source colourspace. Calibration doesn’t, and is not strictly needed either. https://discuss.pixls.us/t/rip-displaycal/21775/130 https://discuss.pixls.us/t/rip-displaycal/21775/130

  No, my correction is correct. Colorimeters are physical measurement devices to adjust the display so that it reports an accurate color profile in the first place for which to color manage to. It's required for the monitor itself to be able to display accurate colors at all.

    > Colorimeters are physical measurement devices to adjust the display so that it reports an accurate color profile in the first place for which to color manage to. No. You can profile an uncalibrated (unadjusted) display and the profile will be correct. There is zero inherent requirement to adjust the display, or for the display itself to report a profile. > It's required for the monitor itself to be able to display accurate colors at all. Also no. Once you have profiled the uncalibrated display, you can accurately display colours within its gamut by converting to the profile.
