I wrote a recommendation about this 7 months ago (oh my, how time flies): https://news.ycombinator.com/item?id=31707222 https://news.ycombinator.com/item?id=31707222 tl;dr: If the TV is working well enough already, it may be ill-advised to connect it to the network. The apps, while convenient, can be supplanted by an external AppleTV or similar for minimal cost relative to a nice TV. This protects the TV not only from being a privacy threat and general ad-ridden nuisance, but also from receiving potentially harmful updates that can lead to performance regressions.
