The depth of the root window is dependent on the display hardware that
you are using.  It is read by the X server from the hardware and is
not settable under software.  It reflects the physical configuration
of the hardware.  From your information, I would have to guess that
you are using a 98547A graphics card which has 6 planes of frame
buffer memory.

Yes, it is hardware dependent.
