60fps has plenty of advantages, but "more detail" is not an objective quality as you stated - and the point I took umbrage with. Like I said, it doesn't magically create more detail than existed in the first place. You can make the case that more frames -clarifies- a detail, but this isn't a 100%, all-of-the-time thing. See for example a game like Dark Souls 1 on the PC, which had its animations designed and keyed for a 30fps cap, where 60fps unveils artificial-looking exaggerations that are obscured by the lower framerate (it also changes the way the animations interact with the environment, breaking cohesion at times).
Similar to running retro games at 240p, there is a degree of intentionality in framerate/resolution decisions that blanket statements about either tend to ignore.
