Larger screens android phones are not the iPhone. IOS has issues with scaling which do not exist on android, and there are plenty of articles scattered around the web that point to this being why apps feel much better looking on IOS..A 4x of a 4inch retina screen would require a 522 ppi 5 inch LCD on the iPhone6 running ios...Whats the size and ppi count of the HTC one's LCD? Apple does not want to get into AMOLED as Samsung and others have done ( its their decision based on other parameters in displays)..So yes this is one compromise that needs to be mitigated for apple. It may not exist for other OEM's.

S5 is rumoured to have an AMOLED display and not an LCD. Nexus 5 and HTC one have LCD iirc...The best LCD display around 5 inches in the "research" world is the sharp IGZO LCD's which was shown off in late 2012 and which has around 498 Ppi. I am yet to see this on a mass produced device, although sharp may have them on a "japan-specific" device but definitly there is no LCD that is 500+ ppi (Like the one which would be required for a 4x bump on a 5 inch device)..
They could have done it years ago, but clearly they did the trade off internally and found that the best way forward was a 4 inch device. And look how handsomly this has worked for them with the 5/5s/5c family and its sales.
What do you mean by they did the trade off internally?
They are doing it..and have been working on it for some time (according to rumours)..Apple takes time with most things. Display tech is not something that advances as rapidly as say SOC tech..
So in conclusion are you saying the reason they didn't come out with it sooner is by design choice? Or by tech limitation?
