If it works it's fine. I have KDE Plasma installed on:
$ eselect profile show
Current /etc/portage/make.profile symlink:
default/linux/amd64/23.0/no-multilib
As you can see, that's not the KDE profile. As long as you have all the packages you want then leave it be. You don't have to use the KDE profile.
