Earlier AMOLED-display Samsung's always been excessive color saturation, but two months ago, the manufacturer introduced its new line of tablet computers Galaxy Tab S, which received AMOLED-display having color reproduction comparable to that of natural. Last week, was announced a new flagship smartped Samsung Galaxy Note 4, which is equipped with a 5.7-inch Super AMOLED-display with a resolution of 2560x1440 pixels. It is in this device, Samsung has brought the technology of production of AMOLED-display to a level that include a special mode "Standard", you get a totally natural color reproduction with real colors.
In color mode "Standard" display color temperature reaches 6596 K, which is almost nearer to the reference value in 6500 K. This means that Samsung has managed to achieve the maximum balance between red and blue, and the third green is present in sufficient quantities, and not excessive as before.
In Galaxy Note 4 color difference of shades of gray and RGBCMY reaches a value of 3.84 and 4.86, respectively; it demonstrates that the final contrast of colors will not deviate significantly from the desired value. Note that the indication of the color difference of less than 5, is generally considered an acceptable norm.
Also worth noting is that the maximum brightness Galaxy Note 4 reaches about 500 nits, allowing you to stay on the text display readable even in extremely bright light.
If you still prefer rich colors, as in the earlier devices with AMOLED-display, then you can always turn on in the settings mode "Cinema" or "photo".
