Probably a silly question but I know the UB820 isn't recommended for file playback but I love its tone-mapping feature. Should I just keep that if I wanna play discs and use the x800m2 for files? Does self-tone-mapping even matter for files, DoVi or otherwise? For reference, I use a ForMovie Theater for display.

Hello everyone,
I have been following this thread for a while now which lead me to buy a sony x800m2
My biggest frustration with this device was all of the clicking that was required to select a movie
I decided I needed a movie wall so I hacked together a prototype this weekend
It utilizes plex for all of the media metadata, posters and file paths
I put together a small python backend + nginx host video files
Cheers!

FEL playback works only with 2 players, the OPPO and his Clone. And FEL will be only triggered if the Source is an ISO file or in the m2ts container.
There is no chance fpr playback FEL within mkv or mp4 container.

Full FEL works on Chromecast w Google TV 4k and Tivo Stream 4k, been discussed here plenty before. I do it myself with both of mine and single stream dual layer FEL in MP4.

Major difference with FEL being processed is that output will be full-blown 12 bit DV. Vs 10 bit when there's no FEL. Change in dynamics and color is noticable, but I can't say I'm overwhelmed. To my eyes, having a tv calibrated yields more awe. It's much discussed how much (and if) the 2 bits really make a difference, since nowadays tv's even can't saturate fully on 10 bit luminance. And very few (if any) are able to process 12 bit with RPU internally. I think it all depends on personal taste and type of (player and) tv. There's people that prefer (10 bit) HDR10+ over DV FEL+RPU. Everybody should decide for themselves, on their own equipment. Which also goes for tv-led vs LLDV, I'd say.
So if I only can playback Single Layer P7 files, then I guess FEL won't be a thing since this will always be 10-bit, right?

LG C7, C8 C9 play FEL in mp4 perfectly.
FEL in not something that can be ignored. On some movies it's 15-20% of the movie size.

You can mux a P7 Dual Layer mp4, thats not the Problem, DV will be triggered. But only MEL will be displayed. There are many Tests in the www, Original UHD BD ISO with OPPO vs. Dual Layer MP4 / MKV. Also Shield Pro 2019 and other players like Zidoo triggered DV with a Dual Layer file, but the playback is only in MEL. Trust me or not, your choice.
You can test it easy, make a DV P8.1 file of the Dual Layered file and playback both. You see no difference. Good movie for testing is Braveheart, superb FEL Layer.

Yes, playback of BL only will be 10 bit.
If FEL can't be processed, of course there's no need for it. Nevertheless it may be convenient to keep FEL muxed. Maybe in the near future FEL playback (in mkv) will be more commonly supported by players. Also, as @daddy mentions, already tv's process FEL properly.
Note that single layer P7 doesn't exist. P7 always carries BL and EL. It doesn't matter whether these layers are interleaved into one videotrack (single track dual layer) or they're carried in two separate videotracks (dual track dual layer).
Two well-known single layer DV files are P8.1 and P5. P8.1 carries a (backwards compatible) HEVC HDR10 baselayer, like you find on UHDBD.
P5 - often delivered by streaming services - carries a (non-backwards compatible) baselayer encoded in 10 bit IPTPQc2 full-ranged colorspace, proprietary to Dolby.

well here's the thing. Plex version 8.something used to playback P7 mkv files. After a couple updates Plex stopped playing back p7 files. One software player tja6t is left, which is playing back p7 files is VIMU. So I guess is just a matter of software. We need a good software player which will playback all dv profiles and display info if fel is dropped etc.

Again Chromecast with Google 4k and Tivo Stream 4k display full FEL information not just up to MEL
You can use those test files to confirm yourself just like me and others have here long ago

That's correct. The only problem with those devices is the lack of Lossless sound support. Does anyone have any info about the new fireTV Cube? Does it also work with FEL titles?

I don't believe it even supports DV7 if I'm reading this correctly.
