Apple backed themselves into a corner with desktop monitors by setting the bar for Retina pixel density so high, display manufacturers still aren't able to provide panels which are that large and very dense and very fast. Nobody makes 5K 27" 120hz+ monitors because the panels just don't exist, not to mention that DisplayPort couldn't carry that much data losslessly until quite recently. There's no excuse for 60hz iPhones though, that's just to upsell you to more expensive models.
