unfortunately Samsung doesn't normally allow that, even the manual which takes up major amounts of space on newer TVs can't be deleted in favour of a system update if you're out of space.
I have 2 7000 series that just won't update and nothing is installed on them aside from the factory preloaded rubbish and the manuals which are bigger than the updates lol.
sorry I can't be of more help, maybe someone knows a way around it but as far as I know it's not possible to remove most of them, only hide or disable them.
