System Details

Windows 10 22H2
Thorium 126

Problem When opening https://jpegxl.info/test-page/ on both Firefox Nightly 131a and Thorium 126, observing the red jpeg xl image shows different results - on the Thorium image the logo in the image is not visible, meaning that the full color range of the image is not shown. On Firefox, the logo is visible.

Screenshots Firefox: ff nightly Thorium: thorium 126

Additional Notes Thank you for your work!

After further research I have discovered that "The red box is actually meant to be blank if you don't have a HDR screen" and the issue is in the FF implementation of the codec.
