org 9.0.9 and FWIW, I see this

	 (gfx-file (ignore-errors (org-babel-graphical-output-file params)))
	 (result (org-babel-octave-evaluate
		  session
		  (if gfx-file
		      (mapconcat 'identity
				 (list
				  "set (0, \"defaultfigurevisible\", \"off\");"
				  full-body
				  (format "print -dpng %s" gfx-file))
				 "\n")
		    full-body)


in org-babel-execute:octave
