Enable Support HDR images 2. Open the attached test case Result: The background extended color `color(srgb 5 5 5)` looks brighter in the HDR layer. But the same extended color looks clamped in the SDR layer. Expected: The extended colors should be displayed the same regardless of the HDR-ness of the layer. Ideally an HDR layer should be created if any extended color is going to be displayed in this layer. Till this happens, extended colors will be clamped. 2113704 1 webkit-bug-importer 2025-04-28 16:19:18 -0700 <rdar://problem/150231788> 2113707 2 sabouhallawa 2025-04-28 16:22:34 -0700 Pull request: https://github.com/WebKit/WebKit/pull/44641 2126901 3 mattwoodrow 2025-06-30 19:36:44 -0700 Pull request: https://github.com/WebKit/WebKit/pull/47418 2127805 4 mattwoodrow 2025-07-03 21:03:32 -0700 Pull request: https://github.com/WebKit/WebKit/pull/47595 2129417 5 ews-feeder 2025-07-11 13:21:23 -0700 Committed 297279@main (fd22b8420d86): <https://commits.webkit.org/297279@main> Reviewed commits have been landed.
