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 / Rec.709 Gamuts. The Color Shifts with APL are very small, with Average Shifts of just 0.2-0.4 JNCD and the Largest Color Shifts of just 0.3-0.7 JNCD for the Gamuts. The White Point Color Shifts with APL for both Gamuts are very small at 0.2-0.4 JNCD.

See the Color Shifts with APL section of the main article for the measurements and details.
See the Absolute Color Accuracy page for an in-depth discussion and analysis of Color Accuracy and definition of Just Noticeable Color Differences JNCD. Display Color Errors less than 3 JNCD on a display are generally not visually noticeable for typical image content and appear accurate to the eye. A 3 JNCD Color Shift is marked in the Figures below.

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.

Figure 4a.   DCI-P3 Color Accuracy Shifts with Average Picture Level APL
The Average Color Shift from Low APL to 50% APL is 0.2 JNCD and the Largest is 0.5 JNCD

Figure 4b.   sRGB / Rec.709 Color Accuracy Shifts with Average Picture Level APL
The Average Color Shift from Low APL to 50% APL is 0.2 JNCD and the Largest is 0.6 JNCD
