YouTube videos have too much sharpness and brightness compared to other web browsers.
I wanted to switch over to Firefox as I've noticed it's better for my PC's overall performance. I tried watching a YouTube video and noticed that the video was sharper and brighter compared to usual.
i've already tried the gfx.color_management.native_srgb = true in the about:config page. I've also tried changing the Radeon Image Sharpening in my AMD Software: Adrenalin Edition as I have an AMD graphics card. No difference whatsoever.
Here's a screenshot of 2 other browsers and Firefox (in the middle) for comparison:
