What is the real difference between 4K streaming and ultra Blu-ray discs? Scott Wilkinson says that most of the Ultra Blu-ray discs on the market are now 4K HDR. Streaming content is making the move to HDR, and several of the TV shows streaming are in 4K. Netflix is the leader in this. Stranger Things is going to be streaming in 4K HDR as well, but it won't be as good because of bitrate. It'll top out at about 25 Mbps streaming, and it's data compressed, while 4K Blu-ray HDR is about 100 Mbps uncompressed. Renting Blu-rays is an option, but finding HDR Blu-rays can be a challenge.
Scott is very happy Apple finally joined the 4K/HDR party with the new Apple TV 4K. Even better, the Apple TV supports HDR 10 and Dolby Vision, and will be upgrading all the movies you've already bought that are in HD. But there is a problem. Your new Apple TV won't support YouTube in 4K since it doesn't support VP9, Google's ultra high definition codec.
Ted is having trouble with his Wi-Fi. Leo says that's not really the fault of his network so much as it's just congested from everyone else's networks and activity. Also, Ted is streaming 4K video and that takes a lot of bandwidth. It may be that Ted's ISP just isn't giving him the bandwidth he needs to consistently get a good stream. On top of that, anything they publish gets cut in half when streaming via Wi-Fi and with the congestion and the bandwidth, that's quite a challenge to overcome.
Lance says that he doesn't think 4K streaming will ever take over 4K Blu-ray discs. Scott says that the median downstream bandwidth in the US is far less than what 4K requires, and even if it did, with data caps, your streaming would be terribly limited every month. Leo agrees and says that he's seen 4K streaming and it's nowhere near as good as a Blu-ray experience. Scott says it's because the streams are compressed and that is part of the problem.
