Honestly, it is up to you and if you think it is a suitable requirement for your living room. Many options with all the features are available in a lesser price range if you eliminate 4K. But, that doesn't mean 4K is not a good feature to have on your TV. The larger displays with high picture quality, great contrast, and high definition can really add to your experience. So, if you are willing to pay extra for that, 4K is definitely worth it.
