I suspect your comment is tangical to the what myself and the GP were discussing as I don't really understand why qt5 using QML would affect the look and feel of existing legacy qt4 applications. Running qtconfig-qt4 and redefining the config I wanted did fix the "ugliness" of qt4 applications after I upgraded to KDE5 (or whenever it was KDE switched qt versions)
