The latest software with pending Wayland color management support for enabling HDR display support is the open-source Google Chromium code for the Chrome web browser.
The merge request was opened yesterday for Chromium to introduce Wayland color management protocol support (color-management-v1) to support rendering to HDR surfaces. This Chromium code has been successfully tested with HDR video playback within Chromium atop the KDE Plasma desktop. With the current code, this color management support is enabled by default.There is a built-in “remote kill” switch if needed though to deactivate the Wayland color management support should problems surface.
“[Wayland]Support color management protocol
This change adds support for color-management-v1. This enables rendering to HDR surfaces on supported platforms. I’ve verified HDR video playback is working on KDE Plasma 6.4.2. A WaylandWpColorManagerV1 feature flag is added and enabled by default, which can be used as a remote kill switch in case we need to disable the feature. Once this lands, the old zcr_color_manager_v1 can be removed.”
More details on this Wayland color management support for Chromium/Chrome via the Chromium code review.
2025 is indeed shaping up to be the year of HDR on the Linux desktop with the many pieces of the Linux stack coming together for High Dynamic Range display support from laptops to gorgeous desktop displays like the Samsung Odyssey OLED G8 G81SF.
