First things first. I wasn't responding to or interacting with you when you copied my first post to the other poster so no goal post moving here plus I never edit what I post because I try to do my research very well before posting and if I'm wrong about something I just admit it and usually just add an addendum below where I was incorrect. I try to never to remove/edit anything (other than for fixing spelling/ grammar or punctuation errors) I've posted if I think what I wrote was correct and if I'm wrong I have a strong enough sense of self to not be too embarrassed to leave a mistake in writing online or admit one the same. This is how we all learn here. In other words thanks for the editorial advice but I'm good with what I wrote earlier and in the context it was written for.
He stated the Sony player had an improved DV picture over the OPPO with both decoding the same HEVC container with the same attached DV XML metadata to forward to the display. He's since reset one or both of the players(I forget which) and now states the pictures looks the same on the display using both players.
The critical bit is "it can't" and yet Apple has* and, if you believe John Archer's version of reality, so has Sony. The latter quote of yours above is confusing but if you're saying "I was wrong before and Apple did fix DV blooming in Netflix content on the LG x7" well then okay.
Thanks, but I'll say what I'm saying if you don't mind
. I'm saying, "Apple hasn't and if YOU believe John Archer's article on the Sony player it was Dolby with the fix not Sony."
"It also seems that, somehow, Sony's 'bespoke' TV and X700 firmware-based Dolby Vision solution fixes previous DV issues with suddenly raised black levels over HDMI."
By the way the idea that a DV stream is an inviolate object is wrong per Dolby. They prefer if you leave them alone and if you break one you get to keep both parts.
I never said you couldn't "screw it up" after decoding but actually making changes to it's data after it's been decoded and improving the picture without breaking it in some way seems like a stretch. Especially since both source devices and sink devices have to sign up for the Dolby Vision Licensing and pass it's testing to be labeled as DV capable. Show me one place in the Dolby Vision White Paper linked below where this latter statement about preference is supported in DV's workings please?
"The Dolby Vision composer is responsible for reassembling the full-range signal from the base layer, the
enhancement layer, and the metadata."
"The display mapper is tuned for the target display device: it knows the maximum and minimum
brightness, color gamut, and other characteristics. Metadata that accompanies the full-range Dolby
Vision video signal carries information about the original system used to grade the content and any
special information about the signal. Using this metadata, the Display Mapper intelligently transforms
the full-range signal to produce the best possible output on the target device."

No, Dolby Vision is not inviolate but it is closed source:
"Closed source software can be defined as proprietary software distributed under a licensing agreement to authorized users with private modification, copying, and republishing restrictions."
The Apple fix in tvOS 11.3 for floating black levels on 2017 LG OLEDS in DV streams is well known. Likewise the change in the same version that enabled DV streams to Sony displays.[/SIZE]
Here's link's to 2 of John Archers articles below stating it was a Dolby Vision EF up streaming through HDMI and a Dolby Vision fix to 2017 OLEDS not an Apple one. Plus no mention of it in the 11.3's release notes.
Back to OPPO. Sorry guys.
