Barring a few devices, all of them seem to do internal processing in YCbCr. It is much easier to manipulate luminance and chroma with YCbCr. It used to be that if you could change brightness/contrast on a display when the input signal is RGB, you could say that the internal processing is in YCbCr. With the newer SoCs used in displays these days, it has become difficult to draw this conclusion. If the manufacturer doesn't specify what the internal processing is, it is almost not possible to test for it in any meaningful way.
