applykgammasettings is only called on login for people actually installing kgamma (it's a separate tarball and separate package on openSUSE at least).
There is no change to plasma's own startup procedure, and no change at all when kgamma is not installed.

kcminit is actually used by kgamma right now (it calls the same function), but that only applies when the user enters the KCM. But the point of this setting is to be applied automatically on login/startup.
