Just noticed something a little odd with current version of OSMC on a Vero4K+.
I run 1080 systems and with 4K mkv files, I need to punch up the contrast as the HDR->SDR conversion is far too muted for my display. Recently, the functionality to adjust contrast within Kodi was enabled, and as this is remembered on a file-specific basis it’s a good solution for me. However, suppose I set the contrast to 60% and stop playback. On resuming playback, the visible contrast has reverted to standard, but if I pull up the Kodi video adjustment menu, the contrast value in the menu is 60% - the moment I then adjust it, the visible contrast adjustment kicks in. So it looks like the stored values of the contrast adjustment are not being used on resume, but they work when adjusted in-stream. I have tried this with several files and behaviour is consistent.
If necessary I can post a log but hoping the problem description is clear enough.
