hdr movies these days can have v bright and dark scenes and sometimes both. even if I choose the darkest shade white for subtitle, it is still too bright on dark scenes, so bright that it can become uncomfortable to watch and cause blooming on some tvs. it will be useful to have a few more darker shade white / grey color options for subtitle text, especially for 1:2.35 movies which I can position the subtitle on the lower black bar on the screen.
