Created attachment 167172 [details] Wide Gamut JXL Photo (P3). SUMMARY *** Test photo from webkit/blink devs and joint picture expert group reveals that Dolphin is missing support for JXL wide gamut (e.g. created by few latests generations of android and apple phones fo some time now). Thumbnail is not displayed at all for this so called P3 photo. No problem in nsxiv. *** STEPS TO REPRODUCE 1. Get the attatched photo 2. Open Dolphin 3. No Thumbnail at all. OBSERVED RESULT No thumbnail for jxl wide gamut photo. Thumbnail should also display webkit logo. If there's red if you fix, but there's no logo then you failed to support wide gamut. In thumbnail there should be a webkit logo on red background. No logo=no support. Here not even red background. EXPECTED RESULT Fix the support for google/android and apple phones and their photos (wide gamut jxl). 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 libpng 1.6.43 libavif 1.0.4 libheif 1.17.6 libwebp 1.3.2 webp-pixbuf-loader 0.2.7 P.S. Gwenview displays thumbnails correctly. There is red background and webkit logo on it. Gwenview cannot display this photo. It displays only red background, but no logo, hence fail.
Hi - this looks like a duplicate of https://bugs.kde.org/show_bug.cgi?id=483380. Can you please check and if so close this one? Thanks.
No. Its not the same, I reported P3 JXLs (see wikipedia for P3). I believe I have no porblem with JXL thumbnails. So please read carefully and DO NOT CLOSE. sRGB, Adobe RGB and... wide gamut= the so called P3 (apple, I think google too). Its supported by $ nsxiv -t *.* without problem (even older sxiv too).

The title says it all WIDE GAMUT.
