I'm not sure if this the right place to post this but I'll give it a shot...I currently have an LG C7 OLED (with Dolby Vision support)...is there a difference in UHD/HDR picture quality from using the LG C7's built in Vudu app versus something like an Apple 4K device when streaming movies?
I keep seeing people rave about Apple 4K (iTunes) but I don't understand...do they use more bitrates in their UHD streams?...is the quality that much better?...what about something like FandangoNow vs Vudu (using the LG apps)?...I always thought streaming quality was generally the same (of course UHD Blu-ray quality is much better) I've never used Apple TV before and was thinking about picking one up if the difference in quality is much better then LG's built in streaming movie apps |

I have the same TV and Apple TV 4K. There’s no difference in UHD/HDR/Dolby Vision quality. The sound quality will be better from the TV’s VUDU app though (depending on the movie and your sound system), at least until Dolby Atmos is added to the Apple TV later this year. I prefer the Apple TV’s UI, though, and own quite a few iTunes 4K movies that are only HDX in VUDU. But if I have a UHD movie both places I always use the TV’s app for the better audio.

A Vudu engineer confirmed on the Vudu forums, the bitrate is around 15 for UHD streaming. When using the xcode developer app from a Mac, you can see that the average rate is around 25 for the 4K playback on the Apple TV 4K. https://forum.vudu.com/forum/vudu/ge...ge3#post382967 |

Besides the increase in bitrate, Apple put a specific focus on quality when making the device using an A10X chip which really does a good job handling HDR10 and Dolby Vision. While Vudu works on a variety of devices, Apple streams video very specifically optimized for their devices. Of course, this is mostly for iTunes films and other providers who encode video streams specifically for Apple devices. (Netflix uses Apple's preferred HEVC spec in their app, Google only uses 1080p H.264 on YouTube because they want VP9 hardware acceleration on Apple devices for 4K). Vudu's streams while good, I don't believe were optimized to take full advantage of the hardware, they're just using their already established HEVC spec which just happens to be supported on Apple devices. They'll probably change up to compete sooner or later.

Note that Apple uses adaptive streaming for UHD content (and also for HD content if you have "quick start" enabled). If your bandwidth isn't sufficient for the highest quality version, you'll get a stream with reduced quality (which may still look quite good).
