As soon as phones, tablets, and hybrid laptops (i.e. surface, etc) enter the picture you can no longer assume RGB because users rotate the device. People now stream PC/console games on their phones, too.

Incidentally 'vertical sync is vertical' is also no longer a correct assumption. In some cases if you rotate a device now the tearing (when vsync is off) is vertical instead of horizontal, which is really disorienting if you're not used to it.
