I can muddy the water for you.  On my VMS 8.3 box (a not new Alphastation
500) I get this:

    richardlo $ xdpyinfo
    name of display:    _WSA2:
    version number:    11.0
    vendor string:    DECWINDOWS Hewlett-Packard Development Company OpenVMS
    vendor release number:    8003
    maximum request size:  65535 longwords (262140 bytes)
    motion buffer size:  0
    bitmap unit, bit order, padding:    32, LSBFirst, 32
    image byte order:    LSBFirst
    number of supported pixmap formats:    2
    supported pixmap formats:
        depth 1, bits_per_pixel 1, scanline_pad 32
        depth 8, bits_per_pixel 8, scanline_pad 32

So I don't have a pixmap format with a depth of 4 either.  But my Redhat
Linux EL6.6 box does, it reports support for 1, 4, 8, 15, 16, 24, and 32.
