The Windows VNC server (WinVNC) will _always_ report 16 or 32 bits per
pixel.  This is because Windows uses colour palettes for displays with 256
colours or less, so they are instead converted to 16 bit non-palette based
format before being transmitted by WinVNC, to avoid the need for clunky
palette-handling code.

Yes.  This is all handled automatically.  It is the responsibility of the
VNC server to produce the format that the client requests.  WinVNC will
happily output whatever format the client requests, despite internally
always using 16 or 32 bit colour.
