I'm not even talking about using a spyder and calibrating it properly, even just manually changing the settings with a printed reference card can be worth a lot (or even by color matching by eye against an iPhone, as those have great default colors). Or even just manually setting the dials until it looks right. But the reality is that I can't use some websites because they chose to make my experience worse so users with badly produced and badly designed devices have a better experience. We're yet again at a situation where obeying the standard is punished.
