@wesk05 @Sam.Nazarko @wrxtasy  Thank you very much for the replies.

I am a little clearer now on a few things but this s905x / s905d 8bit to 10bit conversion is still bugging me. I have found a few qoutes from this forum and some others.

It has already been stated by Neil Armstrong from Baylibre - the guys doing the AMLogic Linux Mainline Kernel work that the AMLogic S912 has a proper 10bit pipeline. All other S9xx HDR capable hardware is doing some dithering.

There was/is definitely dithering and rounding code in the old AML Linux v3.14 Kernel for S905X devices.

S912 has a 10bit pipeline, s905x has only a 8bit to 10bit converter right before the hdmi controller

 

1. Why would Baylibre say s905x and s905d are doing some dithering ?
   
2. If the s912 has a "proper 10bit pipeline" why do you guys think a s912 running CoreELEC is doing dithering ?
   
3. If this is actually a software problem (kernel) then is it that the old 3.14 linux kernel can't output true 10bit ?
   
4. Is CoreELEC using the old 3.14 kernel ?
   
5. Is OSMC using the new 4.9 kernel ?
   
6. Is @wrxtasy build using the old 3.14 kernel ?
   
7. Is the beta build of of LibreELEC 9 using the new 4.9 kernel ?
   
8. Does using kodi 18 or kodi 17 have any affect ?
   
9. CoreELEC uses kodi 18 right ?
   
10. OSMC uses kodi 18 or 17 ?
    
11. @wrxtasy build uses kodi 17 ?
    

I tried @wrxtasy build last night ( 8.2.5.1 ) on my s912 box and 4k HDR autoswitching seems to be working well and terminator 2 was nice and bright.

Are there any advantages to using a Vero 4k+ with OSMC rather than @wrxtasy build on my s912 ? £120 is money I havn't really got.

By the way my TV is a LG B7 and I have a Denon x3400 inbetween the TV and s912
