This is a global local file, not system wide and so not considered as default
cf. https://lxr.kde.org/source/frameworks/kconfig/src/core/kconfig.cpp#0702
if the entry is set system wide 
/etc/kde5rc
/etc/xdg/system.kdeglobals
/etc/xdg/kdeglobals
/etc/xdg/yourcustomfile
~/.config/system.kdeglobals

It will be reverted to the default value specified in the file
