Dual-layer FEL untouched VS Dual-layer MEL converted
https://screenshotcomparison.com/comparison/6565

the untouched FEL is brighter & has more punch, no doubt. But I think this is normal because I'm seeing the same kind(if not more) of difference when I compare the Spears and Munsil FEL & MEL

Spears and Munsil dual-layer FEL untouched VS Spears and Munsil dual-layer MEL untouched
https://screenshotcomparison.com/comparison/6564

Dual-layer MEL untouched VS Single-layer MEL (el+RPU) untouched
https://screenshotcomparison.com/comparison/6566

also from the bluray discs I inspected, FEL DV hevc stream is the actual movie with a white/grey tint on it while MEL DV is just a static white/grey image.
We still can see the video in the MEL conversion so that could be the reason why it doesn't play on the x700. I can add some random MEL track to any HDR10 hevc stream and it will still play in DV (single or dual layer). with some flickering but it triggers DV.


real FEL / real MEL / MEL conversion

x700 vs shield vs firestick vs Chromecast. (use number keys on your keyboard to switch between the image)

SKYFALL MEL DV.... 3 comparisons of each device:

x700 vs Firestick: https://screenshotcomparison.com/compar ... /picture:2

x700 vs Shield: https://screenshotcomparison.com/compar ... /picture:2

x700 vs Chromecast: https://screenshotcomparison.com/compar ... /picture:2

Firestick vs Shield: https://screenshotcomparison.com/compar ... /picture:2

Shield = worse of all, oversaturation and ugly red artifacts everywhere. -----> btw I didn't look for a movie with artifacts, I took the first MEL movie I found and it still had red artifacts.
Chromecast = oversaturation but no red artifacts.


Spears and Munsil, x700 Original MEL vs FEL to mel conversion: https://screenshotcomparison.com/comparison/7017


same method:
-all the players send LLDV.
-Vertex tone map DV to SDR using the same settings.
- The signal is captured using the same settings.

I have a question, why in the first comparative, the fel to mel is more darkness, and now is the same?

Thanks

no, it's the same and I did not compare fel to mel vs original mel on the first quote you are referring to

camera comparison between mel original vs fel to mel: https://screenshotcomparison.com/comparison/6581

Capture card comparison Original MEL vs FEL to mel conversion: https://screenshotcomparison.com/comparison/7017


EDIT:
the comparison you're probably talking about is fel vs mel... I may have messed up that comparison though. It's much easier to do a mistake when i do camera comparison (exposure EG) than the capture card comparison method.
also keep in mind that the camera(lossy) comparisons are amplifying the difference while the capture card(lossless) show the exact difference.

So in your opinion, what comparison is more accurate?

again, the first comparison (london has fallen) is FEL vs fel to mel (in other words: FEL vs MEL)

and the other one is original MEL vs fel to mel. (in other words: MEL vs MEL)

you can't compare those.

I've just made a Doctor Sleep rip (DV and HDR10+) and it's also only black screen on Firestick with Dolby Vision, even though it's MEL.
Might be something caused by HDR10+, because other MEL samples work fine.
