So much info in the thread, so what i gather is by converting a DV mkv with FEL to profile 8.1 we loose FEL?
So it’s the same a playing a DV MKV on a zidoo or dune? FEL is discarded and only the rpu is used?
yes FEL is discarded but know that not every FEL movie can be converted to P8 (or played on non-fel devices) because some of them are expanding the picture brightness when BL and FEL are decoded by the player.
So the DV metadata in the RPU is meant to be played with the FEL brightness ONLY. Playing these FEL movies on a non-fel device will result in an image darker than the intended look.
Thanks for confirming and looking into SPR. I was also surprised that people just brushed this flickering off as purely a problem with playback of P7 DV w/FEL for media players/apps or something, and not the actual retail UHD BD authoring or DV metadata somehow, considering I've basically never come across something that flickered this much and so obviously from frame to frame, or at least it's super rare for a disc to have this. Re-doing my own L1 DV metadata in Resolve for this movie also fixed that issue playing back on Shield Pro for example, which shows it wasn't inherent to the HDR10 BL, but something to do with the FEL/DV and how it was implemented and/or how it's processed, as you confirmed. This movie deserves another pass maybe for an anniversary or Criterion even, so perhaps it will get fixed one day, as otherwise it's a fantastic 4K UHD. Cheers for the work and info!

I'm not sure if this has been pointed out yet, but the option to edit the L6 MaxCLL/MaxFLL based on the HDR10 BL MaxCLL/MaxFLL values doesn't seem to work properly. It seems that it only copies the L1 RPU content light level and uses that for L6 rather than the light level from the HDR10 file.

It works as it should because static HDR10 maxcll/fall are often incorrect or not present.
I made this change a couple of versions ago when @quietvoid added the information in the rpu summary.
You can always use (2-1-1) and edit L6 with any value you want.

no , not without baking the EL into the BL. (require re-encoding)
What do you mean by
putting the el in the bl? Are you talking about generating a DV XML file by resolve and re-injecting it? Like in this tutorial? https://youtu.be/ZdFiqATo_j8
