A media player like nvidia shield or apple tv is just a lot more performant and gets updated for ages. TV firmware mostly gets abandoned when the next generation releases. The interface gets laggy and slow very quickly.
Also, some people have Plex/Kodi setups with a NAS. Not fun to try to play UHD Bluray remuxes on a TV directly.
