citrusui originally asked about DCI-P3 color space, ygra then confused this wider color space with higher bit-depth. Now you want to further confuse everyone by referring to your comment about advantages of 24-bit RGB over paletted colors which is completely irrelevant to the original comment about DCI-P3 color space. DCI-P3 contains colors which are outside of the gamut representable by the 24-bit RGB (which uses sRGB color space).
