Subtitles to bright or picture to dim during 4K playback

I meant the 5 year support I read somewhere but maybe I’m wrong. Not that I think of it perhaps I bought is less than 5 years ago :). I can’t remember.

I’ve tried to apply the hotfix (first one mentioned here) but after that still no new update. Also did a reboot in between.
Latest version OSMC still: November 2020 2020.11.1

I prefer not to do a reinstall.

Any idea? Or should I make a new topic about this? Thanks
