4k videos shine a light at you. Real life most things refract light. Now that in itself doesn’t mean screens are brighter than looking outside on the grass. And our eyes are very good at looking for dynamic ranges of light. But when you take pictures or videos in 4k, often you want to optimize for what the audience sees. And we get good at controlling the scene. And with each pixel being its own light source we can do things like hdr where shadows are highlighted and over saturated skies are toned down to show contrast.
Even if you don’t do hdr, cameras automatically adjust to give a range that is good for display.
