SUMMARY Images are opened with sRGB instead of embedded color profile STEPS TO REPRODUCE 1. Convert image to some other color profile eg. linear prophoto RGB or Rec2020 (e.g. in krita) 2. Open in gwenview and compare OBSERVED RESULT Opened images looks exactly as when you set programs to ignore embedded color profile EXPECTED RESULT Opened images should be opened with the correct profile gwenview 17.12.3, 19.12.3 SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 18.04... 20.04 (available in About System) KDE Plasma Version: 5.12.9, 5.18.4 KDE Frameworks Version: 5.47.0, 5.68.0 Qt Version: 5.9.5, 5.12.8 ADDITIONAL INFORMATION
Opening the test files by Florian Höch (License: CC BY-SA 4.0) on Gwenview 20.04.0 yields the following result: 1. jpg and png test files are rendered as expected with correct colors, color management is working and embedded profile is respected. (I used GIMP to verify that the files have embedded color profiles.) 2. tif test files are rendered with *incorrect* colors, the text "NO COLOR MANAGEMENT OR EMBEDDED PROFILE IGNORED" is shown, which means Gwenview's color management is not working for tif format.

For the test i uploaded 2 files of same scene with different color profiles: https://mega.nz/folder/HA10HCwR#GUfhZbrfGfr8d_idU0guMw Thank you
After looking at the source code, I believe that Gwenview's color management (probably) is only implemented for JPG and PNG, but not TIFF, so I am changing this bug to CONFIRMED.
