Hi. Somehow I accidently signed up to Amazon Prime when ordering a game and got that 30 day free trial. They had some 4k HDR Dolby Vision TV shows that were included for free. I watched some of the Jack Ryan series and too me I wasn't that impressed. I have a Sony 65" 930e with the Dolby Vision update. I do sit 12" away from it but I walked up closer to it and I still really wasn't that impressed. I think all the Ultra HD TV does is make HD look a lot better. I do like having the 65" screen and playing video games on that size screen. Also watching my favorite shows on the 65" screen. It also has six speakers built in that includes two small tweeter and two small sub woofers.
