I keep seeing encodes that take a dolby vision profile 5 stream and combine it with a hdr10 (and/or) hdr10+ stream. I see everyone saying that this helps with compatability. So if you have DV device, it’ll play DV, otherwise it’ll play HDR10/HDR10+.

I have been told that this messes up the original artistic intent of the Dolby Vision Profile 5 stream because it’s using 2 different sources with 2 different gradings. So my question is - if you have a DV device, is the DV profile 5 grading being changed at all from the original? in other words, when it plays back in DV, is it using the HDR10 base layer or is it only using the DV profile 5 info? Hope that makes sense.

I am asking because it seems like ALL of the new DV encodes I’m seeing are in this hybrid format. If it does indeed change the image from the original intent then I have no clue why all of the current encoders are using this format…

    P7 has an additional layer, the enhancement layer. It’s currently not possible (far as I know) to preserve this when encoding, so it is discarded. You end up with the encoded base layer which has the DV rpu injected.
