When I execute your recipe, after the make-frame-invisible invocation
the new frame get minimized, i.e., is only represented on the desktop as
an entry in the task bar (or panel in KDE terminology), and the
frame-visible-p invocation returns t.  Is that expected?    

This is with KDE 4.14.9 and GNU Emacs 26.0.50.3 (x86_64-suse-linux-gnu,
