Yes, you can use a DNS proxy service to unblock content on Apple TV. But it's important to keep in mind that proxy services provide no privacy benefits since they won't encrypt your connection, nor will they hide your IP address. Some premium VPN providers, like ExpressVPN for example, offer Smart DNS services included in their standard subscription plans. By going with such an option, you can get the best of both worlds: privacy when you need it, and seamless streaming capabilities whenever you want.
