AMOLED displays have gotten better, but they're still oversaturated (looking at you, Samsung), so the colors aren't accurate. That's one thing LG/Google actually got right on the 5X--except for the defective ones, the colors were really accurate on its IPS panel. Apple has stuck to IPS displays for the same reason. Active display and battery-saving tricks unique to AMOLED are cool, but it's more important to me to have correct color reproduction.

My main beef is that a lot of them are STILL hard to read in direct sunlight, which is a dealbreaker for a guy who spends a lot of time in farm fields and vineyards at work and on trails on the weekends. My iPhone 3G was easy to read even with the sun at my back in the desert, so it's not like daytime legibility is a new technology.
