Note 9 uses the Super AMOLED Screen. With Super AMOLED, the color is expressive, rich and can be more sensitive to subtle color changes. The color accuracy is high also.
The adaptive display mode of Note 9 automatically optimize the color range, saturation, and sharpness of your display. As each user may have different preferred colors for super AMOLED, if you do not satisfy default screen color, we recommend to adjust full screen color balance of your display to change the appearance of white tones.
