Figure 4a Color Shifts for DCI-P3 Content
Figure 4b Color Shifts for sRGB Content
The Colors and Absolute Color Accuracy of the display should not vary as the on-screen image content changes.
In Figure 4 below we examine and measure the Shifts in Color with changing image content from Low Average Picture Level APL to 50% Average Picture Level APL.
Figures 4a-b show the variation in the Absolute Color Accuracy between Low APL and 50% APL for the DCI-P3 and sRGB Gamut Content. The Color Shifts with APL are very small, with an Average Shift of just 0.3 - 0.4 JNCD, and the Largest Color Shifts are only 0.5 JNCD. The White Point Color Shifts with APL for the 2 Gamuts are both very small at 0.3 - 0.4 JNCD.
Color Shifts with APL
section of the main article for the measurements and details.
The Color Shifts are very small so the Low APL Red data points are almost entirely covered over by the 50% APL Blue data points.
The Average Color Shift from Low APL to 50% APL is 0.4 JNCD and the Largest is 0.5 JNCD.
