Actually, there isn’t. 4K or UHD (Ultra High Definition) are basically marketing terms for the same thing, meaning a resolution of min. 3840x2160 pixels. What you are refereing to is HDR (High Dynamic Range) that adds more color depth to the image. It isn’t dependent on screen resolution and can be found on 1080p screens (or any other for that matter) as well.
