In theory, would they behave differently?
Most likely, yes

@RESET_9999, this is odd. I decided to factory restore my "Cinema" mode, also restore to factory the DOVI calibration profile. I did this bcoz I was curious how does the custom DV Profile & its white balance settings impact image quality.

Using default "Cinema" pic mode, I played on my Oppo the eagle beak test & there was NO more change between the "original" & "no-trim-chroma-weight" shots. What does calibration have to do with trim-chroma-weight handling ? (27s in MOVIE - ip13 DV)

Any other test pattern you can recommend to test Player-led vs LLDV? (not doubting my TV isn’t capable, just wanting to understand)

theres a test file on the SM disc but I can't spot the m2ts.

PS: I did a P5 version of the eagle beak test file: https://drive.google.com/file/d/1F0JPmi ... sp=sharing

I think you've made the P5 eagle so I can play it on my E7 (USB), thank you ! Results are identical between Oppo & E7 usb DV: NO change between 'original' & 'no-trim-chroma-weight' using same file with default 'Cinema' pic mode.

OK I re-applied this custom DV cal profile (Tmax = 759) & boom, there is the clear change between 'original' & 'no-trim-chroma-weight' shots as in Vincent's video & my previously shared screenshots.

idk what that means & if it means anything :|

On Windows Energy Player(400nits edid), the eagle chroma weight also doesn't have a response but it looks like it doesn't need to, the beak already looks bright yellow. But if I use another test file, it reacts to CW.

other CW test files:

On the C2, no reaction at all on any of the test files and the eagle beak looks darker green like in HDR10, not bright yellow as it should.

Which part of the test shows a darker green beak? I haven't noticed any green tint on my C2, which is also calibrated.

In Vincent's video, he mentions green but I also don't see a green tint or color. Though @RESET_9999 mentioned it isn't the color that is important, rather some visible change between the 'original' & 'no-trim-chroma-weight' shots. (see correction in this POST).

DV chroma weight makes the eagle beak bright yellow instead of greenish looking in HDR10. You can see it in @Vincent video and @aboulfad pictures.
On the C2, CW doesn't work and the beak looks more like HDR10(darker yellow greenish)

No, I mentioned that it doesn't matter how it looks in the inaccurate cinema home mode.
The beak is supposed to look bright yellow.

Yeah, in this collection: LG DV Picmode Oppo, you see the green, but that was ONLY when I used inaccurate Cinema Home. When I used Cinema (w LG DV cal profile + 2/20 points settings), both shots looked yellow to me, but the original more yellow.

I'll link when I find the comparison of both shots using Cinema calibrated pic mode: slow pics comparison

Neither of these two files show any change on E7 Cinema (calibrated)/Oppo. Full circle, it seems for my setup I have no conclusive mechanism to check that my TV is in TV_Led.

On my E7, there's some interesting relationship with Cinema pic mode & chroma weight where the default cinema doesn't react to changes, while the calibrated DV profile applied to Cinema reacts to the chroma weight changes. Maybe it all doesn't matter, bcoz you said earlier that chroma weight isn't used that often.

Now that's strange and sounds like my C2 behavior...
What's the original DV config on your E7?

Looks pretty bright yellow to me. Will test it out in HDR10 later, made me curious.
