I don't think so.

You omitted the important part:

  It is used only on frames for which no explicit name has been set
  (see `modify-frame-parameters').

And if I evaluate

   (frame-parameters (selected-frame))

I see there (explicit-name).  So I think your customization is ignored
by design.  I think you should set the `title' frame parameter instead.
