I've never bothered with this setting on my GS4, but I knew it was there. I was happy with the vibrant colors so just didn't bother for accurate colors as I didnt want my screen to look washed out like the LCD screens that boasted accurate colors. But accurate colors don't have to mean a washed out looking screen. This is especially true on an Amoled screen with its infinite contrast. So that being said, I switched my screen mode to movie, and bam! My screen never looked better. I remember the guys at Displaymate saying this, and they're absolutely right. Colors look accurate and pictures and videos still pop. Give it a try if you haven't, you're eyes will thank you for it. I should add, my co-worker prefers the standard setting and slightly more saturation. But the take away from all this is that Samsung should be applauded for the advancements in this display tech while giving us different calibrated modes for choice. How can anyone not appreciate this? Very nice.
