Your average person looks at a screen, make a judegement call on hich is subjectively better looking to them, and then uses buzzwords like "sharp", "pop", "pretty", etc. This isn't meant as an insult to anyone, but it is what it is. Plenty of people think the Galaxy line has sharper, prettier, etc. displays.Correct me if I'm wrong, but aren't the Samsung Galaxy displays "Pentile"? In which case they are undersampling certain colors (typically blue) on the display. I don't see how one can argue that any such display is "sharper" than an IPS display at equivalent resolutions. If Pentile allows Samsung to increase the resolution by more than the undersampling, then perhaps it can be sharper.
OLED probably does provide better dynamic range--and possibly color--than any backlit technology because it is emissive.
