This is more of a feature request, but since it concerns HDR I’ll post it in the Vero 4k section.
Could you please add “Dark Grey” to the subtitle colours?
The reason is simple. When watching HDR content grey subtitles are turning white and I mean WHITE, blindingly white. A remedy for external subtitles is to change the font color to 808080, but that has to be done by hand in every .srt file and it does not help when one uses internal srt-subtitles.
