The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thanks for the report, and for attaching about:support.
Analysis
HDR video playback on Windows shipped in Firefox 153 (bug 2012848), so this is a report against the newly released feature rather than a capability Firefox does not have yet.
The symptom described here is that HDR is never offered at all: YouTube shows no HDR entry in the quality menu, and Jellyfin reports "The video's range type is not supported". Both of those are driven by what Firefox advertises to the page (the video-dynamic-range: high media query and Media Capabilities), so this looks like the Windows HDR display-detection / video-overlay colour path not engaging, rather than a media decode problem.
That makes it distinct from the other Firefox 153 HDR reports currently open: bug 2057570 is specific to AV1 full-range PQ content, and bug 2057786 is HDR engaging only in fullscreen. In both of those the HDR path is entered; here it is not offered at all. Bug 2038112 is the closest match (HDR not offered on an AMD card), but that was an older RX 580 on Windows 10 before the feature shipped, so this RDNA 4 card on Windows 11 is worth treating separately.
Moving this to Core :: Graphics: Color Management, which owns the Windows HDR video work, and adding it to the HDR-video-on-Windows meta (bug 1902427).
Next Steps
The attached about:support is the main artifact needed here, so there is no need to re-send it. Two things would help narrow this down:
-
Please try the standard HDR test video and say whether an HDR entry appears in the YouTube quality menu: https://www.youtube.com/watch?v=vP-ctJUQBws — and whether the result changes in fullscreen or in theater mode.
-
Please capture a profile: open
about:logging, on the Logging presets tab choose the Graphics preset, and under Logging output select "Logging to the Firefox Profiler". Click Start Logging, play an HDR video from a fresh page load, then click Stop Logging — the captured profile opens in the Firefox Profiler. Click Upload Local Profile (the share button) and paste the resulting share URL here. The instruction video walks through it. If you have privacy concerns about the profile or the media content, email it to media-alerts@mozilla.com instead.
One more thing worth confirming: in Windows Settings -> System -> Display, is "Use HDR" turned on for the GO27Q24G itself? Displays that only offer a "HDR video streaming" toggle are not supported by this feature.
Issue was caused by h264ify. Enabling all codecs resolved it.
