I am sure that people have different refresh times in their eyes. I don't consume a lot of video, so the only time I remember noticing a poor video frame rate was when watching Up! in 3-D. I think the theatre just divided the 30fps between the two eyes, and panning shots bothered me so much I had to close my eyes a few times. In every day life I am constantly bothered by LED tail lights, and cheap video projectors. In both cases I clearly see the individual blinks in the case of the LEDs and the color cycle in the case of the projectors. I find in quite distracting. Most people can't even see what I am talking about when I describe it and they go seeking it out.
