When running with HDR dim menu overlay

#1

Not sure if this is possible.
When playing a movie with HDR obviously my LG C8 will crank out a lot of luminance. When I open things like “download subtitle” or the movie info overlay it is really bright.
Would it be possible to auto dim/turn down the contrast of the Kodi overlay when something with HDR is playing?

Is also somewhat related to subtitle brightness and transparency like described in this topic: Subtitle brightness setting

It’s on the list of things to do after we implement kernel 4.x.

If the user brings up the overlay, we can just fall back to SDR (via sysfs).

The downside of switching back to SDR is that the TV also needs to switch which will result in blank screen for a period. Like switching resolution and frequency when video starts playing.

No, that can be done on the fly. But the right answer is pre-adjust the OSD so that when it’s mixed with the video the colours (of the OSD) come out the same as if it was HD/SD.
