Ok! When you said " all 24p content is output with YCbCr 4:2:2", I wasn't sure if you meant just 4K or actually "all" content no matter the resolution.

Actually that is exactly what I meant. When you set the output resolution to 4K, ALL 24p content is output as YCbCr 4:2:2. I will need to check what happens in 1080p setups.

Update:

On 1080p systems, your color space options are:



As for refresh rate switching behavior, the color space remains the same as the one selected under "Display & Sound" -> "Advanced Settings". If you select YCbCr 4:4:4, it will be YCbCr 4:4:4 after the refresh rate switch. Same with YCbCr 4:2:2. It is only with 4K where it changes to YCbCr 4:2:2
