fake TV-Led mode? how?
The convert process.
Dv profile 7 =BL+EL+RPU -->Convert to dv profile 8.1 = BL+ RPU → this process make dv almost hdr10 except it sends label to tv to tell tv that is DV video
No, the only time P8.1 will be worse than P7 FEL is when the FEL expands brightness:

All amlogic products are affected？
Yes and the Realtek too.

If TV has a proper HDR tone mapping, this is a minor problem, maybe?
This obviously isn’t a criticism of coreelec team as it’s not their fault but starting to wonder if the homatics was actually worth the purchase if DV is never to be able to play back my 4k rips that I’ve done.
Is there a simple way to confirm if a 4k BD has mel or fel etc? My rip that I did for Dune (1984) for instance show as this in mediainfo:
In the case of DV, the RPU is used by the display for tone mapping. The signal sent out in fake TV-Led mode has already been processed by the player once, as in the case of LLDV. Double RPU processing is not good in any case.
So I’d rather use LLDV instead? Then TV knows it’s box-led and do the necessary things.
Yes. Use LLDV.

Interesting, on my Dune rip it shows as MEL whereas the mediainfo tool just says EL, you’d assume they use similar libraries to look up this info.
There are no players that are really doing this at its full extent. Your only solution is to buy a Blu-ray disk player and play your Blu-rays directly or use it as media center.
It’s odd, does anyone know why UHD BDs use a specific profile that nothing seems to support? (going off topic here)
It is supported by Blu-ray players for which it was intended for.
I meant nothing other than the BD players.
It is basically Dolby’s market strategy.
The convert function, just touch with the profile 7 with Fel layer. All other dv format stay intact.
And not all, bd rip have the second layer, its just just part of all bd movie. Coreelec play it on the highest quality was possible, in the amlogic processor side.
So currently, when using CE on Homatics Box R 4K Plus box - it’s best to enable the player led DV mode in CE settings?
