I do have a 4K TV, but the 4K content doesn't play smoothly. I have compared the content from the native TV app and the box. The box plays the 4K content in a laggy manner. Also, the channel freezes and doesn't change on changing channels from the remote. I had a very bad experience, and Tata Play didn't bother to fix the issue. They said the Binge+ would perform in that manner. I am really fed up with Tata Play. I have a normal HD box, and in that box, I am not getting some channels that I have subscribed to. It's 3 days now, and they cannot fix it.
