You linked to a wiki page that has nothing to do with subtitles.
I gave you the correct link.

That link is incorrect.

The setting GUI peak luminance in HDR PQ mode is found in System -> Display see https://kodi.wiki/view/Settings/System/D...DR_PQ_mode

It is under Display since it limits the peak luminance of the entire GUI as well as any overlays rendered by Kodi, and this includes subtitles.

This Setting is currently only avaiable on Windows.

It is really an important feature while HDR/Dolby Vision is more and more common nowadays.
Especially for those Android-built-in TV sets.
