Comment (by Balling):

 >The FFmpeg 5.0.1 behavior is correct (the input and output files are
 identical), and the FFmpeg 5.1 behavior is incorrect (the input and output
 files are not identical).

 What matters is applying correct transfer and primaries on your original
 file: https://imgur.com/dZpH9xj

 This is screenshot from Davinci and is color managed to BT.709 (so gamma
 2.4) scene + BT.709 primaries from your s-gamut3-cine + s-log3-cine file.
 Again, this is the way to do it.


 Again, check e645a1ddb90a863e129108aad9aa7e2d417f3615.
 You are not color managing the image, so what are you expecting?
