Apple has shared new details about display technology in a recently published white paper focused on the Studio Display XDR. The document explains how Apple plans to improve color accuracy and long-term calibration for professional users who rely on precise display performance for editing, production, and color-critical work.
The company says a future macOS update will introduce a feature called Full Calibration. This tool will allow users to recalibrate important display characteristics using professional measurement equipment. When used with a compatible spectroradiometer, the feature will adjust the display’s white point, primary color coordinates, luminance levels, and gamma response. Apple confirms that Full Calibration will not be available at launch, but it will arrive in a later macOS update.

According to Apple’s Studio Display XDR Technology Overview white paper, the display also introduces a new color measurement system called Apple CMF 2026.
Apple CMF 2026 Improves Color Accuracy
Apple created Apple CMF 2026 to improve how displays measure and reproduce color. Most display calibration today still depends on the CIE 1931 color matching functions, a model developed nearly a century ago to describe human color perception.
Apple says the older system has limitations that sometimes cause displays to look slightly different even when they follow the same calibration standard. Apple CMF 2026 aims to reduce those differences by matching how the human eye actually perceives color.
Each Studio Display XDR receives individual factory calibration using Apple CMF 2026. At the same time, Apple continues to support the traditional CIE 1931 system through its reference presets so professionals can maintain compatibility with existing workflows.
Apple also says it is working with the International Commission on Illumination to help develop a broader industry standard based on this research, which aims to improve color consistency across displays from different manufacturers.
