Subtitles count towards the HDR-ness in a HDR video

[thany]

In a HDR video with subtitles, the subtitles are always rendered at maximum brightness, which will cause the monitor to brighten part of the rest of the video, causing it to become washed out slightly.

I would like to see either one of:

• The subtitles somehow do not count towards the total amount of light calculated by the monitor, for it to calculate the brightness of its lighting zones. Probably ain't gonna happen, this one.
• The subtitles are rendered at whatever lightness is currently being displayed in the lighting zones they are positioned in. Not sure if possible. But it would fix the problem, at least the way my simple mind sees it :)
• The subtitles are rendered in pure white at the lowest brightness. They will seem grey (same as the white mouse pointer), but at least they don't cause the scene to wash out.

It also bears noting that I've played with the settings, but not a single setting, other than completely hiding the subtitles, makes for literally any difference in how they are rendered. I can't even get them to show in yellow, nevermind the "subtitle output" setting. The whole settings panel seems non-functional to me.

Of course, restarting the video also doesn't help. Should it? I'm not even sure when settings are supposed to be applied. I expect after hitting the Apply button. And yes, of course I've checked that this filter is actually the one being used.
