Well, good question. But what's the point of releasing those titles from the same studio (e.g. Disney) in hdr10 then? The only thing I can think of is licensing fees, but ... seriously?RESET_9999 wrote: ↑Mon Jul 26, 2021 7:46 pmI think most movies are graded in single deliverable HDR workflow(DV or hdr10+ or both) and HDR10/SDR are just derived(trim pass) from the HDR master. so the static BL is the same, thats why it works (perfect brightness match with p5)...chros wrote: ↑Mon Jul 26, 2021 6:30 pmI'm not sure what you try to do is correct (injecting p5 RPU into hdr10 streams), and I don't even mean the color issue: it would be correct, if they would use the same mastering process for the streaming and the UHD-BD version. But I think that's not the case.
And if the UHD-BD is created in hdr10 (or hdr10+ recently) in mind, then the whole movie is graded with a static curve and the dynamic p5 rpu will modify the look the wrong way.
Theaters get a different grade and that make sense because of the lower luminance of PJ. But 1 grade for streaming and 1 other grade for bluray releases? sounds like a waste of time and money when you can do it in just 1 grade.

Don't get me wrong, it the result is looking better, then why not use it, we don't have a clue how it should look anyway
Thanks, that was an interesting video. Here's a good video from a french colorist, talks about DoVi workflow, manual SDR grading, fake HDR, and the end (from ~48 minutes) is also really interesting (He has the same clips graded in various formats on his website lelabodejay.com)
To add another variable into the mix
We know now that Firestick also triggers TV-Led Dovi with 2018 LGs, but the whole image is noticably darker, e.g. compared to internal apps.
Here's the profile 8.1 version of Spears's black clipping DoVi pattern, so I fired it up on FIrestick and Oppo as well (Plex didn't recognised it, dunno how that works):
- Oppo: 72 barely flashing
- Firestick: 81 barely flashing!!!
But it's not just the low end that is affected, the whole image seems to be a bit darker, it's like double-expanded is set in madvr ...
So, guys, if you like, you can also try this out (in a pitch black room) with your display and other devices to see how they behave.
