Figure 1b Color Gamuts in 0 to 2,000 lux
Figure 1a below shows the measured Color Gamuts for the Samsung Galaxy S10 along with the Standard sRGB / Rec.709 and DCI-P3 Color Gamuts. 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.

The Reduction in the Color Gamut with Ambient Light
For the sRGB and DCI-P3 Natural Modes:
Figure 1b. sRGB Natural Mode in 0 to 2,000 lux Ambient Light
The Gamut is reduced to 89% at 500 lux 77% at 1,000 lux 61% at 2,000 lux
Figure 1b. DCI-P3 Natural Mode in 0 to 2,000 lux Ambient Light
The Gamut is reduced to 88% at 500 lux 78% at 1,000 lux 62% at 2,000 lux
Figure 1b. Vivid Mode in 0 to 2,000 lux Ambient Light
At 500 lux, which is typical bright indoor lighting, the Galaxy S10 Vivid Mode Color Gamut shrinks
so that it is a better match to DCI-P3. At 1,000 lux the Vivid Mode is a better match to sRGB.
