Ultra‐Wide Color Gamut Displays: How Far Have We Come in Rendering Real‐World Colors?

ABSTRACT Wide color gamut (WCG) displays mark a significant and timely evolution in display technology, enabling high‐fidelity color reproduction that extends well beyond the limitations of legacy color spaces. This study explores the color range of real‐world scenes and examines the extent to which real‐world colors fall outside the sRGB and even the more modern DCI‐P3 color gamut. It further evaluates the capability of OLED displays with ultra‐Wide Color Gamut (ultra‐WCG—referring to a gamut larger than DCI‐P3) to accurately reproduce these colors and identifies which color areas remain unproducible on such displays. The results show that a significant number of real‐world images fall within the boundaries of the sRGB and mostly DCI‐P3 color spaces. However, certain colors, such as cyan, pure green, or highly saturated reds and yellows, fall outside these gamuts, which suggests that some ultra‐WCG displays, such as our test vehicle (a QD‐OLED television) enable more accurate reproduction of a larger, more impactful portion of the colors we encounter in real life, without needing the full gamut of BT.2020.
