It's not really the same thing. Things might start at some similar starting point and get expanded/filled in, but higher PPI certainly plays a role. Plenty of people can still notice a difference with PPI in the 300 range and that which is higher than that.Screen resolution in pixels is irrelevant as long as it is a Retina display with more than 300ppi (for a phone). What counts is the resolution in points and comparing this the XR has the same resolution as the Xs Max! You can read about it here....
