You're making a lot of incorrect and dismissive generalizations. If you're able to notice the differences in color calibration and film grain, more power to you. Most people can't explain the difference between the saturation in video when watching something on a phone compared to watching it on their TV, if they even detect it. For what it's worth, I just did a Farnsworth-Munsell 100 hue test and got a perfect score again. I'm not sure why telling apart fingernail polish shades would make a difference in how meaningful or noticeable changes in saturation or film grain are to people. Readability is dependent on screen brightness and difference in contrast between background and foreground colors. These decisions aren't based on what engineers assume matters, it's dependent mostly on A/B testing and perception psychology. It's the same kind of research that went into making the OPUS audio codec and deciding which parts people will notice missing and which parts don't really make a difference. Tiny to moderate changes in visibility/readability make a much smaller difference than you imagine. https://www.colorblindnesstest.org/farnsworth-munsell-100-hue-test/ https://www.colorblindnesstest.org/farnsworth-munsell-100-hu...
