From the screenshots you sent me it seems that an ATV in DV mode is outputting standard DV which may well be IPT since it shows as purple on a non-DV screen. If it was LLDV it would have the right colours Those implementing the HDFury EDID trick to show LLDV on non-DV screens can attest to that.
Yes - I think my ATV 4K is outputting STD DV not LLDV in this scenario - not something I was aware it did! (For some reason I thought the ATV 4K was LLDV only)
Weâve been working on some improvements.
- @thechrisgregory - you should find that the video stream that didnât play at all should now play as expected.
- Brightness should now be improved.
You can get these improvements by running the exact same commands as before.
Those instructions are here: [TESTING] Vero V: IPT colour space conversion - #39 by sam_nazarko
Looking forward to your feedback
Cheers

FWIW my Philips TV is now reporting master display luminances and (default P3) primaries. AIUI profile 5 doesnât include primaries, MaxCLL or MaxFALL as static metadata.
Just checking âŚ
You need a space before the -O kernel.deb. Iâve corrected the instructions.
Yep, found that, thanks Graham âŚ
Yes, so the regression I saw on one of the video streams (Specifically item 16 in the list of 4K(UltraHD) Formats. - Dolby Vision 10-bit HEVC 23.976fps (filename - âLG Demo DolbyVision Trailer.mkvâ)) has gone, and this displays as expected.
Profile 5 content looks OK for me, I think the brightness is OK, (I couldnât really tell the diffference).
Still seeing the over emphasised artefacts on the âBlocksâ & âArt of Essenceâ demo/test streams - is that maybe a deliberate marketing ploy ?
Otherwise looks good to go, at least from the small set of test files I have used.
Thanks for the feedback.
Has something changed with the update from a few days back? Now my DV titles are purple and green again 
Did you make sure to update from the repo as well as downloading the kernel.deb?
I was just on the mainline one. Hadnât installed the test builds but all had seemed fine.
Need the test one then?
You donât need to be on the staging repo. Just follow all the instructions in Samâs post above.

Spotted some strange behaviour when playing back the DV âmystery boxâ profile 5 test file (and others) when selecting/deselecting some of the OSMC skin menus. I recorded a short video on my mobile (sorry about the poor quality/focus LOL!) to show the behaviour (may be it is expected ?)
The video is breaking up quite badly when switching the OSMC overlayed menus.
I also evidenced some âpink flashingâ overlayed on top of the menus (profile 5)
Not expected but also detected by us. So far no findings what is causing it.

is this just for DV profile 5 or might there also be improvements for HDR10 to SDR?
Sorted now. There is quite a marked difference between hdr10. The colours on the Netflix splash are much more muted and donât really pop at all
There are no changes to HDR-SDR tonemapping in this update.
Are you playing this from disk or streaming? Streaming isnât supported. If from disk, could you upload this sequence somewhere for us?
I would say the contrast is slightly lifted from before and looks much closer to the DV5 content from Netflix. I have no issues when playing a file and moving around the menus. Will look at other files I have later but this update is an improvement.
