You've got to look at how the software uses the extra pixel real estate, though. The iPhone was designed with a high PPI screen in mind, so all the icons and content have been scaled up to be higher resolution - and the way apps are executed means the image rendered re-scales based on the app's design. Windows is not like that; whilst the OS itself has a setting to allow the UI to scale in such a way, individual applications do not necessarily use this setting - and just look really small with high resolutions.
