People really put too much emphasis on the formats than necessary. The difference between HDR10, HDR10+ and DV isn't that much and Samsung TVs aren't missing out on much by not supporting DV.
On the contrary, if the TVs get brighter and better the need for Dolby Vision will get lesser as you won't need tone-mapping to begin with.IMO we still don’t have a display that shows the full potential of DV. For now any tv that supports HDR at best will do.
Hahah now itself I don’t find the need of DV well that’s just me. I do have the Dolby vision demo disk and when it’s played through nvidia shield it plays it in HDR format. I also played the same video in the tv Dolby app which plays the same video in DV. I am happy with both and don’t miss DV.If pple like Samsung tv they should just buy it and not fuss much about DVOn the contrary, if the TVs get brighter and better the need for Dolby Vision will get lesser as you won't need tone-mapping to begin with.
On a TV with 4000 nits brightness for example, every single scene will look exactly the same on DV and HDR10 as it can natively follow the PQ curve.
DV is only active if the TV can't display the content properly.
The shield 2019 has Dolby Vision. I guess you mean the 2017 version?So as DV is dynamically adjusted frame by frame as compared to HDR then if we have any device which supports HDR but not DV (like shield) do we lose the frame by frame mapping Specifically in less bright TVs. Does the movie is DV gets played in HDR and loses out on the frame by frame tone mapping.
@dillihifi Actually, upon further research I've found some more information.The shield 2019 has Dolby Vision. I guess you mean the 2017 version?
Regarding how it plays on displays that don't support it, it will depend on the player. For example, on a PC it plays but the colours look all wrong as the PC thinks it's an SDR video and hence the mapping is wrong. Skin looks purple and green(attached screenshot). The original screenshot was over 7MB at 4k, had to scale it to 25% (540p) to fit in the site's requirements.
Some devices might not even play the file full stop. That's why I don't like DV stuff as compatibility is a massive pain. This file can only be played on my TV via Plex. And even that doesn't work as firestick doesn't pass 4k 60 DV to my TV, so I only get HDR10 (but at least the file looks alright).

recently mobiles coming with hdr10+,atmos even at 15k budget ,does hdr 10+ really works in mobile?(lossy)@dillihifi Actually, upon further research I've found some more information.
There are (obviously) two types of Dolby Vision encodings:
It just happens that I have a copy of such a file for the Knives Out movie, which plays perfectly on my PC despite being DV as there's an HDR10 compatibility layer. Also, MadVR dynamic tone mapping works wonderfully with this movie.
- Single-layer, where the file is played like a Dolby Vision file. The above example is one such example. Hence a device that doesn't support DV can't play the file correctly or at all. Here in the above screenshot, you can see that the player is interpreting it as an SDR video (BT.709 primaries). This is the type you'll find with Web services like Netflix or Disney since they'll just serve the HDR10 version to displays that don't support DV.
- Dual-layer DV where there are two video streams. This is for the compatibility layer in Blu-Ray players so if the display is HDR10 only, it will play the HDR10 compatibility layer. If you play a dual-layer DV file in a player which doesn't support DV, it will play the HDR10 version discarding the DV metadata.
Obviously, it works. My OnePlus 7 Pro with Dolby Atmos can destroy any non-Atmos home theatre system in sound quality and loudness. Even my neighbours feel it when the ringtone produces the full surround dome around my society, with Dolby written in the air.recently mobiles coming with hdr10+,atmos even at 15k budget ,does hdr 10+ really works in mobile?(lossy)
how can we identify content playing on hdr 10+ ?is logo appear like on TVObviously, it works. My OnePlus 7 Pro with Dolby Atmos can destroy any non-Atmos home theatre system in sound quality and loudness. Even my neighbours feel it when the ringtone produces the full surround dome around my society, with Dolby written in the air.
In all seriousness though, they are just formats and when they say it's an HDR10+/DV or has Dolby Atmos, it just means that the phone can play those formats or has some tuning by Dolby. Even 30k TVs have Dolby Atmos and Vision, but their displays and speakers are garbage anyway.
which tv give better DV ? which tv u prefer over qn90aThere is no standard with Dolby Vision.In market you will from 300 nits-3000 nits having Dolby Vision. Anyone can get it by paying a fee.it was 3 dollars last when I checked.
Just focus on 2 things brightness and contrast.a 300 nits DV tv is not gonna beat a QN90A. even if you use quantum computer for picture processing and hire the best engineers to fine-tune the DV algorithm.
this is what Rtings says "Ultimately, the difference between the two formats isn't that important. The quality of the TV itself has a much bigger impact on HDR"
