I really hope the next nexus is not an LG. The nexus 5 is a nice phone for the money, but LG always seems to pick awful displays. Especially in comparison with other nexus/google devices.
I am not an LG fan and with a passion.
But i've been pleasantly surprised with N5 and its screen. its bright even at low settings, sharp, and big. The only complaint I have is that off-axis, it certainly does look washed out. But even if you're looking at off angles from the side, or from where the LED notification is with it laying down on the table, it is undeniably an IPS panel. I think people on XDA were saying they could have used a polarizer to avoid the wash out effect from off axis. but not a deal breaker for me.
The stock calibration is a bit warm too, but not yellow (I guess it depends on the panel lottery, I've seen some N5 that are urine yellow) but with Franco's kernel it looks more saturated and whites look whiter
I've liked N5 screen a lot more than the handful of times I played with a Nexus 4 at the stores. I think they stepped their game up considerably.
And I like AMOLED for videos (from my experience with Galaxy Nexus two years ago) and the blacks are black, but for some reason on the UI and icons, it looks too cartoony for my preference.
Didn't realize Moto X was not pentile though, that's awesome!
