Hmmmm. My idea of diminishing returns isn't really what you describe in OP... I view it as more not being able to notice the graphical difference as much, so jump from ps3 to ps4 not as big as from ps1 to ps2, rather than "there's too much detail and I don't stay around enough to appreciate it."
But I'll say it's not really affected me yet, I still think new games look fantastic compared to games from a few years ago, and putting detail into every incidental area that the player may not even view or may only see for mere seconds IS fantastic. I don't want to go round a corner they don't expect anyone to go and be greeted by a bare empty grey room. Great detail in every area of the world is good design.
