Figure 1 below shows the measured Color Gamuts for the Galaxy Note7 Screen Modes along with the Standard sRGB / Rec.709 Color Gamut in black. The outermost white curve is the limits of human color vision - the horseshoe is the pure spectral colors and the diagonal is the Line of Purples. A given display can only reproduce the colors that lie inside of the triangle formed by its primary colors.

Accurate White Point
The dots in the center are the measured color of White for each of the Screen Modes along with the D65 Standard White, which is marked as a white circle. To deliver accurate image colors for standard consumer photo and video content the display must match both the Standard Color Gamut and the Standard Color of White.

Four Galaxy Note7 Screen Modes
The AMOLED Cinema screen mode is an accurate match to the DCI-P3 Standard Gamut that is used for the new 4K UHD TV content. The Basic screen mode is an accurate match to the sRGB / Rec.709 Standard Gamut that is used to produce most current consumer content. The AMOLED Photo screen mode is an accurate match to the Adobe RGB Standard Gamut that is used with high-end digital cameras and advanced imaging applications. The Adaptive Display screen mode has the Widest Color Gamut and is intentionally vivid. See this Figure for the Absolute Color Accuracy measurements for the Screen Modes.

Note that some of the Screen Modes are similar and their Gamuts and White Points overlap in the Figure. The white circle marking the D65 White Point is covered by the very accurate White Points for the AMOLED Cinema, Basic, and AMOLED Photo screen modes. The Adaptive Display screen mode is intentionally bluish.
