You could try the new Beta Kodi v19.0 Matrix release.
Maybe there is an updated Linux Kernel used that would output different results.
Isn't tonemapping handled by part of the SoC on AMLogic devices? I guess a newer kernel may have more AMLogic tweaks - but I thought HDR<->SDR and HDR10<->HLG etc. conversion was handled at the SoC level rather than in software (due to the large amount of processing required - - or is that a false assumption? (You're converting a video stream of 15Gbs if you're tone mapping 3840x2160 60fps 4:4:4 10-bit content)
Or am I totally wrong? I though that was why tonemapping differed between different AMLogic platforms in how it performed (as different SoCs implemented different algorithms to do so?)
