You get all of the above. Moana 4K steelbook includes the 4K UHD bluray (with HDR), the standard HD bluray, and a digital code for Movies Anywhere. On Movies Anywhere you can view it in 4K Dolby Vision (the best digital format), HD, or even SD. This all depends on what television, streaming device, and internet service you have. So long as you have a bluray player or method of streaming it and or plan to upgrade to 4K in the future you can buy this now and not need to purchase any new media in the future. Well at least until the inevitable 8K version someday...
