I might make a different comparison:

Everyone who has played more than one video game knows that some just feel better than others. In one, your character is fluid and nimble, and in another, slow and clunky.

This is the result of many things, but a large portion comes from input lag and frame rate. More advanced users aren't necessarily more perceptive, they're just better at pinpointing what they're reacting to. (And in some cases, conscious of how an experience could be improved.)

This is similar to the study of any type of art. Whereas a casual observer might look at a painting and say "meh, I don't like it", someone who has studied art pedagogically can describe precisely what isn't working for them.
