P3 Webkit Logo on Red Background Should Be Visiable

STEPS TO REPRODUCE

1. Open Gwenview
2. Click the attatched photo.

OBSERVED RESULT
JXL wide gamut photos (P3) cannot be displayed. It should display webkit logo on a red background. This is a test from google/webkit/blink and joint picture expert group (google phones, browsers, apple phones can make such photos, importing and viewing them in KDE will fail). There's no logo. NO LOGO = FAIL.

EXPECTED RESULT
Fix the support for google/android and apple phones and their photos (wide gamut png, aka P3- see wikipedia, you know there's not only Adobe on this world...adobe srgb...). Webikit logo on Red should be visible. If there is no logo, then there's no support. NO LOGO=NO SUPPORT.

SOFTWARE/OS VERSIONS:
KDE Plasma Version: 6.0.1
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
Graphics Platform: X11
Graphics Processor: Intel Only

ADDITIONAL INFORMATION:
$ pacman Qs 'xxxx':
kdesdk-thumbnailers 24.02
kdegraphics-thumbnailers 24.02
ffmpegthumbs 24.02
qt6-imageformats 6.6.2
kimageformats 6.0.0

P.S. Gwenview displays thumbnails (click "browse" in top left) correctly. There is red background and webkit logo on it, but Gwenview cannot display this photo. It displays only red background, but no logo, hence fail.

Unknown filetype?

Hi - I've tried loading this on the latest Neon but the filetype seems unknown. Can you confirm whether you would expect any additional codecs to be required to view this? Thanks
