Here's a way of finding out if your playback device is processing the FEL or not.

mp4 FEL DT-DL sample: https://drive.google.com/file/d/1PszHwO ... sp=sharing
TS FEL ST-DL sample: https://drive.google.com/file/d/1caOej3 ... sp=sharing
mkv FEL ST-DL sample: https://drive.google.com/file/d/1KV7lqA ... sp=sharing
mp4 FEL ST-DL sample: https://drive.google.com/file/d/1AYrRZo ... sp=sharing
TS P8 SL RPU sample: https://drive.google.com/file/d/1fNW6gE ... sp=sharing



These files are a mix of a BL and a random FEL track. This makes the FEL data visible on top of the BL when played in DV so it easily tells us if the player just ignores the EL or if it actually uses it. The P8 SL sample also has the same random RPU metadata.

Results:

x700 FEL playback = visible FEL
C8 FEL playback = visible FEL
Shield FEL playback = No FEL data visible
p8 SL file = of course, no FEL data visible at all on all my devices

So this confirms that the Shield is not decoding the EL and is just using the dynamic metadata.
Also, the new update does not fix the red push issue :(

look for the FEL noise and compare it with the p8 sample which will be clean of noise :

C8-fel / C8-p8-rpu / shield-fel / shield-p8-rpu / x700-FEL / x700-p8-rpu

Image Image Image Image Image Image
** please do not compare the colors of these pictures. this was just to show the FEL . I did not take time to get the same frame, lock the exposure etc...

Kudos on the ingenious testing method! Unfortunately, the Shield ignoring EL was confirmed to me by an Nvidia staff as well. Not a shocker, but was still hoping for a surprise support nonetheless. Regarding the red push, where are you still seeing it on? I know it's still there for p7 DV rips, but I was under the impression that it was fixed for streaming content when they removed the BT2020 tag from the RGB signal. I haven't looked too closely or really cared to honestly, but curious to what you're still seeing.

OLED CX9LA: no FEL visible, test ST DL FEL.ts can´t be played, test DT DL FEL.mp4 to dark.

UBK90: FEL visible at test DT DL FEL.mp4, p8 of course not, test ST DL FEL.ts can´t be played

as I wrote before :roll:

I would like to add some info reagarding LLDV mode. Turns out there is a bug in Dolby SDK for all UHD Blu-ray players (and oppoclones as well)
This bug leads to noticable picture quality loss in LLDV mode like muted colors, limited brightness and various artefacts.
Probably you already familiar with this video by HDTVtest: https://www.youtube.com/watch?v=e_a77zJTrO4
Sadly Vincent Theo is wrong in conlusion. Difference caused not by additional data from TV but by a bug in Dolby SDK

Shield TV and FireStick and probably any other DV capable device (exept UHD Blu-ray player) are free from this bug

So yeah... fellow Bravia owners there is not so many options for us to enjoy DV besides streaming :D

X700/Oppo/Panny - FEL is used, dimness, bugged picture
Shield TV - FEL is ignored, red push
Fire TV Stick - FEL is unplayable, low specs for UHD backups

Is Zidoo the only viable option for now?

The Zidoo doesn’t support FEL either as far as I know

yes, I was talking about the DV rip from uhd-bd, I checked the Dr. Sleep sample quickly after the update.
In fact, any DV file that is not genuine profile 5 from the streaming services has the red push issue. (p7 p8 p4)
P5 playback on the Shield is not as color accurate as my x700 / C8 but the difference is negligible: I don't think I would notice a difference without the picture comparisons.
I almost never use my Shield though, I prefer my x700 for Netflix and Amazon because of the frame rate match. I know there's a couple of people on the Nvidia forum that says they're seeing issues with p5 as well. I know there are no red artifacts on Dr. Sleep Movies Anywhere / shield.

Where does the information in the SDK come from?

If it is finally so, I understand that the SDK, Oppo and similar players will get an update to fix it, won't they?
Can you put test images?

thanks

yep, just sell that TV and get an LG lol.
Even Dolby recommends to the colorist the LG C7 or newer for previewing.

yes, when switching from HDR10 to DV, my LG gets from YCbCr 12bit to RGB 8bit (LG UBK90 <-> LG OLED CX9LA), first time I´ve seen this I wondered.
the method Dolby Vision (DV) uses to transport the signal over HDMI is referred to as “RGB Tunneling”. The 12-bit ICtCp DV signal + Metadata is encapsulated inside the regular RGB 8-bit video signal. The DV “tunneling” carries 12-bit YCbCr 4:2:2 data in an RGB 4:4:4 8-bit transport. This is possible because both signal formats have the same 8.9 Gbps data rate requirements.

Thank you agneva for the tests. But I asked specifically for FEL vs FEL-to-MEL converted titles. But after reading the above discussion, I guess there won't be much difference between plain HDR and MEL titles. It's such a shame that I need to get another external device to enjoy DV even after having best TV(CX) and best streaming device (shield pro) :(

. Bc
Would (none LLDV) Blu-ray players plays on the Sony?
Vertex2 in the equation.
Here is another up date I also have 2 Philips Blu-ray 4K players 1 doblyvision 1 is not.
And with doblyvision on LLDV for a none LLDV player plays the FEL in hdr10 bl over bl layer what the hell. How is that possible?
It’s also utilizing the Rpu as welll.
Sample file/reset9999 & Lexyz gladiator fel sample displays fel & Rpu over base layer in hdr10. On none LLDV doblyvision player.
Will do a capture for comparison.
So u guys can add Philips 4K uhd doblyvision player to the list plays mp4 rips dl & muxed sl dv.
But no LLDV ability
As u can see from the photo fel is being played Along with the hdr10 when in LLDV mode. Player can’t play LLDV
So in that case who’s decoding the fel the tv or the uhd player?

I can confirm my X800M2 plays P7 FEL (I can see the artifacts with FEL DT-DL sample). I had to get close to really see the artifacts, though (my normal viewing distance is close to 15 ft so maybe that is why).

My guess is no but I have yet to use a source that does not support LLDV. My TV is the XBR75Z9F which only does LLDV. I currently use a Sony X800M2 and Roku Ultra (2020) as my external DV sources. My only other external source is a HTPC w/madVR (HDR10 only). I have also used an Oppo 203, Sony X700, FireTV 4K Stick and Apple TV 4K on this TV at some point in the last year and all played back (LLDV) DV just fine (of course only streaming profiles on the ATV and FTV).
