Dumb LG tv network features

I’m curious if anyone has ever tried to get any kind of control over a network connected dumb LG tv? I have a 47LM4600 that can access DLNA content over the network, and I can access a basic page via the browser, it even shows up on my network as a media player like my pioneer avr. This makes me think there might be some kind of control that can be done over the network. Any thoughts?
