Despite many people asking about calibration, I couldn't find an answer to the following (imo important) question:
Why are so many displays incorrectly or un-calibrated, in other words inaccurate, even when they can display a whole specific color space like e.g. P3?
Are all displays simply individually different in how they show colors (across the same bunch of the same model – meaning every produced monitor is different) and not just a little bit? Because otherwise they should show the right color, shouldn't they – or are different displays so different that they need different files for controlling how much electricity gets through for the display to show the correct color (yes, I have no idea what exact input the actual final monitor gets – neither that, nor where in the display/rendering pipeline the custom/default 'color assignment files' (ICC ?!) sit) that manufacturers don't care enough to do a simple calibration once for every monitor model and put that file into every one of them or their drivers? Or are they simply wrong on purpose to show the normal users those 'vivid' colors that are just wrong (and could theoretically be simply reset (somehow) to just show the actual color values the computer sends)?
Maybe someone knows more than me and/or can find actual good sources regarding this.
Sorry that I'm not entirely sure about the workings of all the connected topics.
PS: To clarify: I'm talking about the light the display emits, not what we, as viewer, perceive because of natural human and environmental influences.
