Actually there are two problems:

1. The above mentioned problem occurs only on non-GTK builds.
   When I tried to use xprop for a maximized frame its output was:
   _NET_WM_STATE(ATOM) = _NET_WM_STATE_MAXIMIZED_VERT, 
_NET_WM_STATE_MAXIMIZED_HORZ

2. On GTK builds there is another problem: evaluating

   (set-frame-parameter nil 'fullscreen 'fullscreen)

   modifies the frame parameter `fullscreen' to `fullboth',
   not to `fullscreen' as requested.  In this case xprop outputs:
   _NET_WM_STATE(ATOM) = _NET_WM_STATE_FULLSCREEN
