Also, from my limited experience with a single OLED screen, it seems that most stuff was created for a certain kind of screen without as much colour fidelity, and now that stuff seems far more...obnoxiously "saturated"?...on an OLED screen.
This has gotten much, much better, especially with "tandem OLED" where you just stack two of 'em on top of each other. It should be fine these days.

That's up to the display manufacturer to calibrate the screen. The content should just be what it is and specify its colorspace properly. (Note, "properly" depends on the environment around you, so if you really care about this you have to participate too.)
