AI summary — not a quote
The Ugoos AM6B+ is considered a niche, enthusiast-grade media player valued almost exclusively for its ability to provide full Dolby Vision Profile 7 (FEL) support and lossless audio passthrough. While it is praised for stutter-free playback of high-bitrate 4K remuxes, it is widely described as a high-effort device that requires custom firmware (CoreELEC) and technical tinkering to function correctly. It is frequently used as a secondary device alongside an Apple TV or Nvidia Shield because it lacks the polish and app support of mainstream streaming platforms.
Pros
- Full Dolby Vision Profile 7 (FEL) playback support when running CoreELEC
- Lossless audio passthrough for formats like TrueHD and Atmos
- Smooth handling of high-bitrate 4K Blu-ray remuxes without stuttering
- Effective tone mapping for HDR10 and DV content on projectors
Cons
- Requires a complex setup involving CoreELEC/CPM builds to reach full potential
- Poor quality stock remote and buggy HDMI CEC performance
- Unpolished and 'ugly' user interface compared to mainstream OS options
- Lacks support for standard commercial streaming apps (Netflix, etc.)

Foe ripped content I use Ugoos AM6B+ that tonemaps HDR10 and DV to lower max. brightness which makes the content brighter on a projector.
I love my Ugoos. CoreELEC is such a fabulous system! I thought FEL playback (CPM builds, etc) were available in 3 or 4 devices... but the AM6B+ is usually a/the top recommendation.
If your looking for dolby vision profile 7 FEL there is only 1 option (outside of physical blueray): The ugoos am6b+ box is the only one that supports it and it needs to run corelelec (kodi).
I’m told that if you want DV FEL support then you will need the Ugoos am6b+ running CPM coreELEC build.

AI summary — not a quote
The Panasonic UB820 is widely considered the benchmark 4K Blu-ray player for home theater enthusiasts, praised for its automatic HDR switching and superior tone mapping capabilities. While it is frequently cited as the 'least bad' option in a market of flawed players, it is highly valued for its ability to play discs that skip on other hardware and its excellent upscaling of standard Blu-rays.
Pros
- Automatic switching between HDR10, HDR10+, and Dolby Vision
- HDR Optimizer and tone mapping features are highly beneficial for projector users
- Excellent upscaling performance for standard Blu-ray discs
- Includes 7.1 analogue outputs for older audio setups
Cons
- Significant physical footprint, with some users comparing its size to a launch-model PS5
- High price point compared to budget or entry-level 4K players
- Occasional reports of 'temperamental' behavior with specific discs despite its premium status

Felt like I was not getting full value out of the TV without a quality source so I ended up buying a UB820 and have never looked back.
I wanted to watch 4k BluRay so I bought a Panasonic 820. Visually I'm all set.
A Denon 3800 is supported by a Panasonic UB820, PS5, Fluance RT82 and Apple TV for streaming.
For 4k playback, I am big fan of the Panasonic 820, but for more budget minded system look to the Panasonic 450.
I have a Panasonic 820 and it is quite impressive how well it plays back standard BluRays.
