This statement is partially correct (well all phone's who's OS isn't color managed) and partially wrong:

Should user calibrate and profile their displays? That's another discussion and has nothing to do with whether an OS is color managed or not.Īs to your statement about iOS and Android, it's not fully accurate and further, if you look, Android (which I have no desire or knowledge of IS supposed to be getting (or has recently had) OS color management: That preview may or may not be ideal, but it is color managed. And that's how iOS works and again, it is fully color managed. All that's required is an OS that recognizes a descriptor for a display (right or wrong, EDID or otherwise) and the scale of the numbers in a document via it's embedded profile (or without, make an assumption, usually sRGB). That color managed OS then produces a color managed preview with that data (display using monitor compensation). One doesn't have to calibrate and profile a display to make the OS color managed it either is or it isn't. You can take an iMac out of the box, it's color managed and in all the above cases, the user never HAS to calibrate and profile that display, a profile exists and more importantly, that OS IS color managed.

You can buy a Mac today and it's OS is color managed. You can hook any display up to it, the OS is still color managed. The facts are, iOS IS color managed and has been maybe since day one but for a very, very long time. Some iOS devices are OLED, some differ, device drift has nothing to do with the ability of an OS to be color managed. You don't have to be concerned about factory calibration because it's utterly moot! And there is measurement data I've seen and have been published that show multiple iOS displays of differing kinds well below JND.
