Now if you're buying a display, are you going to ignore measurements and just go with whatever looks good to you? Hopefully not. Even if you prefer bluer tones or higher contrast, you'll want to know numbers for white point, color accuracy, and contrast ratio. You won't just eyeball it in a store. You definitely wouldn't trust subjective reviews where someone says, "This display seems more contrast-y and blue." It shouldn't be any different with audio gear.
