How can resolution even be "overrated"? Sure it's marketed to hell by gaming companies but I don't think anyone out there actually thinks games don't look good if they're under 4K or 1440p, not even PC gamers despite what many people claim.
It's not "overrated", there's many cases where resolution makes a game look significantly better. Just like there's many cases where an increase in frame-rate or more detailed graphics make a game more enjoyable.
