Is it possible to add Sharpness control in Video settings?

i wanted something to add custom color settings for steam deck perfect settings for steam deck oled in display settings gamma not the extension 0.95 gamma apply system wide apply extension settings brightness 101 contrast 134 saturation 190 takes effect as soon as you play a youtube video.

Addon simply works immediately. You can adjust colors, e.g. on YouTube, video. Usually colors have reduced saturation, and even contrast, e.g. from cameras, old movies. You can brighten dark places. And in bright lighting, sometimes there is no black and dark colors at all. And it does not work globally. I recommend.

Extremely helpful to make the video more pleasant with color corrections! The channel-specific setting option is simply a dream. Would recommend it to anyone who values a beautiful video saturations!!
