There are 8 instances of that message total.
It turned out KDE Plasma will fail to properly render a lossy JPEG XL wallpaper with an embedded color profile.
For the test, I shrank the wallpaper to a reasonable 5120 × 5120 size and convert the PNG to lossless JPEG XL format via "cjxl -e 1 -d 0" command. According to the test run on GNOME Boxed F44 KDE edition, the wallpaper renders as expected. The loading time should be smaller for low powered devices despite a 10+ Mib size.
