Multiple Screen Modes and Color Management
One very important capability of the Galaxy Smartphones that is often overlooked by many consumers and reviewers, is the set of user selectable Screen Modes that are available under Display Settings, which we cover and measure each one in detail below. Most Smartphones and Tablets only provide a single fixed factory display Color Gamut and color calibration, with no way for the user to alter it based on content, personal preferences, running applications, or Ambient Light levels. A very important capability provided by the OLED Galaxy Smartphones is the implementation of Color Management that provides a number of user selectable Screen Modes, each with different Color Gamuts and levels of Color Saturation and display calibration based on user and application preferences. Color Management with multiple and varying Color Gamuts are a very useful and important state-of-the-art capability that all manufacturers will need to provide in the future.

Color Accuracy Plots showing the measured Color Errors for the 41 Reference Colors for each Color Gamut.
In order to see the high Color Accuracy, the Display Setting for the Screen Mode needs to match the Color Gamut for the content that is being viewed. All of the reviewers that continue to rant about the poor Color Accuracy of the Galaxy OLED displays have failed to set the proper Screen Mode for their content, which is very accurate as shown in our extensive Lab Measurements and Viewing Tests.
For all of the calibrated Screen Modes, the Galaxy Note8 has uniformly Very Good to Excellent Absolute Color Accuracy, which are covered and measured individually below. See our detailed
Absolute Color Accuracy Plots with 41 Reference Colors for the 3 calibrated Screen Modes and also this regarding
Bogus Color Accuracy Measurements.
New Four Selectable Screen Modes and Color Gamuts
The Galaxy Note8 has four user selectable Screen Modes: Adaptive Display, AMOLED Cinema, AMOLED Photo, and the Basic Screen Mode, which matches the Standard sRGB / Rec.709 Color Gamut that is used for producing most current consumer content. See this
Figure for the Color Gamuts of all the tested Screen Modes and the
Colors and Intensities section for the measurements and details. Note that the Adaptive Display screen mode is the standard and factory default Screen Mode. Use Display Settings to switch between the other available Screen Modes. We discuss each of the four tested Screen Modes next…

Figure. The larger DCI-P3 Color Gamut and wider range of more saturated colors are also useful in many advanced imaging applications, including HDR High Dynamic Range (below).
The measured Color Gamut of the AMOLED Cinema screen mode is a very accurate 104 percent of the Standard DCI-P3 Color Gamut, and the measured Absolute Color Accuracy is a very accurate 3.4 JNCD, which is very likely considerably better than your living room 4K Ultra HD TV. The Galaxy Note8 is one of the first displays to reach full 100% of the DCI-P3 as the result of using a new high saturation “Deep Red” OLED. See the
Color Accuracysection and the detailed
Color Accuracy Plots for the measurements and details. Select the AMOLED Cinema screen mode using Display Settings – it is not the default screen mode for the Galaxy Note8.

White Point for the Adaptive Display screen mode has an intentionally bluish 7,582 K Color Temperature. A new feature on the Galaxy Note8 is a user adjustable White Point with Color Balance slider controls that allow users to change color of White for the Adaptive Display screen mode. The slider controls allow the White Point Color Temperature to range from 6,800 K, which is close to the Standard D65 White, up to 8,800 K, which has a strong bluish tint that some people like. So with the Galaxy Note8 you can set the Color of White that you prefer.
Figure shows the measured decrease in two Color Gamuts with increasing Ambient Light, from 0 lux, which is perfectly dark, up through 2,000 lux, which corresponds to typical outdoor daylight in shade.
At 500 lux, which corresponds to typical office lighting, the measured on-screen Color Gamut for the Basic screen mode falls to 91%. At 1,000 lux, which corresponds to very bright indoor lighting or outdoor daylight with an overcast sky, the measured on-screen Color Gamut falls to 78%, and at 2,000 lux the measured on-screen Color Gamut falls to 61%. This loss of color saturation and wash out in Ambient Light is well known to all display users.
The way to improve the display color accuracy and performance in Ambient Light is to start with a larger Color Gamut, like the Adaptive Display screen mode, which is shown on the right in this
Figure compared to the Basic screen mode on the left. At 1,000 lux the Adaptive Display screen mode provides a much better match to the sRGB / Rec.709 Color Gamut than the Basic screen mode. The Adaptive Display screen mode also provides a good match to the DCI-P3 Color Gamut at 500 lux. So the Adaptive Display screen mode provides more accurate on-screen colors in moderate to high Ambient Lighting than the other calibrated Screen Modes, which are designed and calibrated for Low Ambient Light. Applying Dynamic Color Management based on the current Ambient Light lux level in the future will able to further improve color accuracy over a wide range of Ambient Light levels, which we discuss further in the Conclusion.

Too bad Apple won't give you these options..........
Furthermore,
· 4
Color Gamuts and 3 Calibrated Screen Modes with
High Absolute Color Accuracy based on our extensive Lab Measurements.
· A new larger full
100% DCI-P3 Color Gamut and Digital Cinema mode that is also used for 4K Ultra HD TVs, so the Galaxy Note8 can display the latest high-end 4K video content. The DCI-P3 Gamut is 26 percent larger than the Rec.709 Gamut that is used in 2K Full HD TVs.
· The Galaxy Note8 is certified by the UHD Alliance for
Mobile HDR Premium, which allows the Galaxy Note8 to play the same 4K High Dynamic Range content produced for 4K UHD Premium TVs.
· A larger
Native Color Gamut with a new high saturation “Deep Red” OLED, resulting in a very impressive 112% of DCI-P3 and 141% of sRGB / Rec.709 Gamuts that also provides much better on-screen Colors in High Ambient Light.
