Could consider probing for kde/plasma similar to how gnome3 is done, via dbus,
candidates include:


plasma5:
qdbus org.kde.plasmashell /MainApplication
org.qtproject.QtQCoreApplication.applicationVersion
matches string "5.*"

plasma4:
qdbus org.kde.plasma-desktop /MainApplication
org.qtproject.Qt.QCoreApplication.applicationName
matches string "plasma-desktop"</pre>
