I doubt it matters. The FTV Stick 4K Max also got CM v4.0 support through firmware upgrades.
AFAIK devices that support Dolby Vision in Android always bundle Dolby's proprietary library, and I guess it's not always kept up to date.

I'd like to notice that "RPU p8.1 L1.L2_cmv29.Edited.3696" test triggers picture adjustments for all trims except probably ms_weight on ShieldTV+Bravia in LLDV mode.
Not sure what ms_weight should change and where to look.
Other versions of L1.L2_cmv29 doesn't work on ShieldTV in LLDv properly.

L11 remains the same, without adjustments.

Hey mate, question. Can your script inject DV metadata from a DV release into an HDR10+ release, is that possible? Or does HDR10+ have to be converted to DV?

yes sure.
The script can also be configured to remove HDR10plus while injecting in case someone use a device that don't like when the video has two dynamic metadata..

Reset, after baking the BL and EL (with DoViBaker, I presume), what are the steps to get the original RPU converted to P8?

Did you succeed with the conversion to P8?

Finally tested LLDV on the Shield(developer mode) + C2 and got some interesting results...

LLDV (player-led)
L2/L1 works fine
even L2 chroma weight works!!!!
CMV 4.0 (L8) no longer works(L2 works) but only for profile 8.1... strangely p8.4 works...
Multi-pattern performs much better in the colorspace conversion and clipping but blue still has banding (as noted before)
red push: no change, as bad as TV-LED

TV-LED
L1/L2 works fine except L2 chroma weight which has no effect
CMV4.0 works fine
Multi pattern has a lot of colorspace conversion/clipping issues.


So I think it's actually better to force LLDV on the Shield.

Sorry for the stupid question.
When I perform clip or file analysis in DaVinci, which color space do I choose P3 or BT 2020?
Having set the color space:

Everything you need is in the tutorial video and BTW, that is not how your resolve project should be set.

or just import my resolve DV preset:

Can you please explain what Multi.Pattern.1000nits P8 DV HDR10-newTVs.mp4 color space conversion box is supposed to show ?

Using ATV4k->Infuse (P8 to P5)->LG OLED E7, I see 2 rows green and red, with flashing squares inside that don't extend to the end, and the red row has a solid red patch roughly 1/3 the row size on the right. Is there an overall description of that test pattern somewhere ? Merci : )

wowsa, merci beaucoup ; ) I guess buying the UHD4K S&M disc once it's available is a must. I will read the super long page and learn. I take it out of the 6 images, the x800 should be the reference ? is the x800 a camera shot of the C2 or C8 ?
