Rated 5 out of 5 by from Incredible performance I have had my bluray for a few weeks now. I have watch maybe 10 - 15 movies and am not just satisfied but vary pleased. For the price I don't think there is a better unit.

Rated 3 out of 5 by from OK as a 4K blu-ray player This is OK for 4K Dolby Vision and Atmos but the setup options are less than needed. No option for Simplink off and SmartShare doesn't work on the network.
Date published: 2018-07-26
Rated 5 out of 5 by from Setup is straightforward. I did a lot of research and decided on this model. Future options enabled and easily upgraded-via wired or wifi. Plays 4k and handles standard bluray no problem. Color is spot on. Easy to use with well thought out menus.

Does the Netflix app support Dolby Atmos and Dolby vision? Does this have Amazon Prime video app? With Atmos and vision?

Asked by: Johnedwardii
The only apps on the LG 4K Ultra-HD Blu-ray Disc™ Player with Dolby Vision®, Model # UBK90 are the Netflix and YouTube apps. Netflix does have some Atmos and Dolby Vision movies to stream, but it's a fairly limited selection, and you'll need a plan that supports Ultra HD (4K) streaming. Amazon has announced that Dolby Atmos will be coming to Amazon Prime Video on August 3, and they recently rolled out Dolby Vision content as of June 27, 2018...^IFV
