I have tested on pdfcairo, pngcairo and wxt terminal on gnuplot 5.1 (cvs, 2015-05-19) (windows version) 
and upload a zip archived file.

http://www.geocities.co.jp/tmgpltwin/Files/Files.html#0064


0064 test.zip, 105,699 bytes, 2015-05-22, zip archived test files on cairobased terminals on gnuplot 5.1


The file test.zip inculdes
test.pdf produced by your script.
test.png produced by your script slightly modified for pngcairo
wxt.png screen shot of wxt terminal by  your script slightly modified for wxt


I cannot find the difference of three images.

Yes. The wxt terminal uses cairo and pango libraries internally like other cairo based terminals.
