When I first turned on my tablet today the first thing I noticed was the screen was a bit dull or more on the warm tone. Specially compared to my note 3. It looks like nvidia added a color correction setting in the display settings. There are 2 presets (sRGB and native). To have a more cooler or bluish hue, select "native". For a warmer more yellow screen select sRGB (default). I prefer the native myself as it is more closer to my note 3 screen.
