Not really. The cost of removing the injectors, then sending them off, then getting them cleaned, then putting them back... Not worth it IMHO, especially as you'll have to find another 6 injectors to use in the meantime. Definitely worth doing if you've got a set that have been sitting around for a while or have ordered from a company where that could be true, then at least you'll know they're immaculate before putting them in.
On a daily driver I'd just chuck a bottle of injector cleaner in once a year for peace of mind, along with a can of 10K Boost.
