How come the colors are undersaturated in the Iphone?
They aren't, the colors are oversaturated on a SAMOLED. I have a Samsung Fascinate and the contrast is beautiful, but the colors are admittedly somewhat oversaturated.
Can apple make their Iphones with Exynos SOC and have retina display with Super Amoled plus tech?
IT would be a beast!
A few things wrong with this...
Exynos is made by Samsung, Apple designs their own SOC
SAMOLED is tech by Samsung not Apple
There isn't a SAMOLED retina screen in existence, only pentile.
Is retina screen a specific technology or is it a coined term for "pixels so small I can't see them with the naked eye?"
Retina is basically whatever specs apples devices happen to have at that given time.
This. Apple changes the definition of retina display around

No, he is right the colors on the iPhone 4 and 4s are as under saturated as the ones on Super AMOLED screens are over saturated. If your goal is accurate colors you shouldn't be looking at an iPhone.

PPI is a straight up measurement that has nothing to do with screen size. 300PPI is the same on a 3 inch screen or a 300 inch screen.
