As I’ve said countless times before, we’ve got OS support for tonemapping HDR content onto SDR displays, now we need OS support for tonemapping SDR content onto shitty displays.
I don't need accurate colors when reading text, but I need it to be comfortable. It seems having color calibration would actually suck for me if I can't adjust brightness depending on the weather, on the hour of the day, on the season, on whether I'm tired or not, or on the location I currently am, or on what I'm doing (reading, programming, or watching a video). I need to be able to adjust brightness without fuss.
I guess I would buy dedicated hardware and put it in a well lit-controlled room if I needed accurate colors.
I want accurate colors because setting it up is a pain, and switching between accurate and inaccurate colors takes your eyes quite a while to readjust.
It’s much easier to just have everything in an accurate color mode and have content designed for that than to switch it around.
Proper color profiles are actually even more of a benefit for cheap displays than good displays as cheap displays profit from proper colors even more.
Until we get HDR on the web, one sRGB size must fit all. At this point, accessibility and readability are top priority. You can always tone down your backlight, while someone else might have it at full blast and still not be able to read without squinting in the sunlight on a cheap display. I know who I'm more sympathetic to.
