At least back in 2021 Apple was still using Metal (their Vulkan-like graphics API) and OpenGL for system-wide compositing, not sure if it changed or not lately?
The choice of graphics API is largely inconsequential. Both Vulkan and OpenGL have the necessary metadata extensions nowadays, but they do need to be implemented with the underlying window system.
Still I am not sure how this provides HDR-like experience on SDR display (may be by using dynamic mapping?)
I've made a statement related to that, when someone insisted that HDR is somehow fundamentally different from SDR: https://gitlab.freedesktop.org/pq/color-and-hdr/-/issues/40#note_2785741 https://gitlab.freedesktop.org/pq/color-and-hdr/-/issues/40#note_2790213 Steve Yedlin's video is worth watching: https://www.yedlin.net/DebunkingHDR/ Apparently https://gitlab.freedesktop.org/pq/color-and-hdr/-/issues/40#note_2845056 was a good watch, too.
