Can someone provide a deeper explanation about exactly what this property represents please?

Does this represent the range of YCbCr values _into_ a YCbCr-to-RGB conversion (in other words, the range of values in the framebuffer), or the expected output range from the conversion?

The color_range/encoding props are about the input. The plane output is generally full range RGB, but presumably some driver could choose to use some other internal format as well.
