Sony is using a low power DV profile that decodes streaming... Archer at Forbes etc and the rest are left embarrassed having gone on the record and hyped their advanced preview of seeing Dolby Vision work on the A1E... to much hyperbole that Sony couldn't fulfill. The rub is X1E TV owners, because of the year long wait, wanted to believe the DV the Sony TVs would get was going to be the "best" DV ever seen... unfortunately, as it stands today, its the poorest implementation of DV ever seen.
So the compensation for the embarrassment is to state Sony is using some "new" DV, which is simply not true. Sony is currently using a discounted low power version of Dolby Vision that can handle streaming level bitrates. Dolby drafts versions bitrate specs for their formats such as Dolby Atmos: the Dolby Atmos you get over VUDU is at a much lower bitrate than what you get on a 4K UHD Blu-ray disc. But the low bitrate streaming Atmos and the high bitrate disc Atmos both are recognized as "Atmos" on a compatible AVR. Sony for DV is using the low bitrate implementation, as far as Sony's obligation, they always said they would offer DV, and they did deliver, it's just they took advantage of guys like Archer etc presumption they were previewing something more than they were.
Spiderman: Homecoming is a Sony Pictures title, the 4K UHD delivering Dolby Vision... How is it that Sony's so-called flagship TVs and 4K UHD player CAN'T play this movie back in it's full presentation quality?!?!? From the excuses given thus far, the Spiderman disc is not mastered in this alleged coveted "low profile".
Where this gets extra wacky with Sony is their ST5000 sound bar allows DV pass-through HDMI ports?!?!?
Dolby Vision over HDMI has to be able to handle processing of the top "full" Dolby Vision profile which other manufacturers installed a dedicated chip in their TVs to do (this has been since 2016 LGs and Vizio).
Sure, the hardware can do the heavy lifting, and what that means is there needs to be some kind of DV profile "down conversion" on the player side to dither the DV data to the lower powered profile so the Sony implementation can recognize it.
I don't believe an OPPO 203 was designed with the processor to do such conversions, perhaps Sony's new 4K UHD player will offer the external DV prep processing. I have 2 of Sony's first 4K UHD player and they both crash within 1 1/2 movie playback.. both ST5000 sound bars had to go in for servicing and both had to have their main boards replaced due to random malfunction. Good luck to Sony selling a DV processing set-top-box.. I'd rather have a dedicated DV chip personally, but..
There may be a silver lining here in that this lighter Dolby Vision can be pushed out to many older displays and projectors as a FW update granted a player like the Sony, or a top shelf gaming console like the PS4 Pro and Xbox One X has more than enough GPU power to do the DV down conversion to meet the low profile standards Sony is first to employ.
But the message is clear, if you want the full "real" Dolby Vision, you should invest in a TV with a SoC with a dedicated DV processor (LG, Vizio, TCL).
I'm betting the A8F has a dedicated DV processor hidden next to the X1E chip, that would be the worse move Sony could make instead of just standing by their software DV implementation... streaming DV is what most people will watch anyways. I think anyone really dedicated to DV content on OLED (I am one) would have already invested in at least 1 LG unit since 2016 that can do it.
