Earlier quoted context omitted.
What about the other very large group, like me, who can easily tell the difference but it's very much not worth the price of admission?
Exactly. I can easily tell the difference and couldn't care less. Brightness, pixel density, and contrast/blacks (including glossiness) are what I care about in terms of image quality. Maybe if I were a gamer it would matter, but I couldn't care less about how smooth scrolling or cursor movement is. It doesn't change my productivity or affect my comfort at all.
Edit: I never got around to my point, which was even though I'm part of the group who doesn't really care about refresh rate, it appears that my body might care.
