Oled TV with the highest color volume?

Which tv has the best color space coverage among oleds, from all the measurements posted online, I see the Sony A9F has the highest P3 and Rec. 2020 color space coverage among oleds, although it still doesn't cover 100% P3, is there any oled out there that does better in this regard?

This is a Bad question Color Volume isn’t all its cracked up to be.
Having owned an OLED 55” C9 it’s color Volume is less than a Samsung Q90R or a Vizio Quantum X on paper, but in real life the Colors on the LG OLED, destroys the other two TVs period.

Oh bad question is it? Then why is it measured? It is infact a relevant metric for HDR, just like peak brightness. While peak brightness measures the intensity of "whites", color volume measures how bright/saturated individual colors on screen can look in HDR. Currently HDR content uses DCI-P3 in a Rec 2020 container, and not the entire Rec 2020 space, so the higher coverage of DCI-P3, the better. And the question I asked was related to oled. Among oleds, which tv is able to put out the highest color volume? I don't think you answered that. Based on seeing the measurements posted online, it seems to be the sony A9F, but is there anything better?

As most know, LG makes the panels for all OLED TVs sold in the US.

Does Sony have some clever way to get a larger color volume out of their LG panels? rtings tests some of their models as better than LG, but are the differences visible to a human eye?

All have the same Colour volume as all uses the the same oled panels the same year.

Lg W8 65" Wall paper oled tv. Sources Oppo 203. Panasonic UB9000. Apple 4K tv. Xbox one x.
Lg E6 65" 3D oled tv... Sorce Oppo 103D

Because color volume, when applied to TVs that use the same set of color filters, becomes little more than an euphemism for brightness.

All OLED panels (from any given year) are the same.
Software differences account for a small variation between the brands, but one can't squeeze much more out of a panel without compromises.

If this comes down to which is the brightest, that is probably the GZ2000.

I'm not asking peak brightness (peak brightness is the intensity of white light output), my question is regarding color volume, I'm asking highest P3 and Rec 2020 coverage among oleds, the GZ2000 from the measurements I have seen has slightly lower P3/rec 2020 coverage than the sony master oleds.

Sony has the highest OLED color volume by the numbers. OLED panel manufacturer is irrelevant. How the panel is driven is what matters.

And which sony model would that be, A9F? Last year when rtings did the A9F review, they said the A9F had the highest color volume they had measured on an oled tv. Has any oled this year upped that?

2018 and 2019 Sonys measure the same outside of individual panel variances. The difference is visible when side by side to my A1E or LG OLEDs. However it is not night and day.

Call me naïve, but I'd expect that the drivers would produce essentially the same result, at least for static imagery.

I have not had the opportunity to compare Sony and LG OLEDs of the same model year.

I guess you're naïve then

Apart from sony not pushing the white subpixel as hard as other oled manufacturers, they also claim to be using their original panel controller on master series oleds (A9F, A9G) that improves color reproduction at high brightness, they refer to it as pixel contrast booster https://www.sony.com/electronics/pic...#pixel-booster

The rtings.com 2% screen peak brightness tests strongly suggest that Sony is indeed "not pushing the white subpixel as hard". Look like LG may be prepared to sacrifice color saturation for peak brightness. The rationale is partly that specular highlights tend to be white-ish.

I know you've calibrated a lot of them, and I trust the Sony is very good. But measurement-wise, it appears the LG is nearly as good. The differences seem to be within the margin of panel variance.

Compare these 3 images:

https://i.rtings.com/images/reviews/...-itp-large.jpg
https://i.rtings.com/images/reviews/...-itp-large.jpg

Keeping in mind that the C9 and the E9 are the same TV. Sony does appear to be a bit ahead in some shades and a bit behind in others, but so do the C9 and the E9. So it's in the same range of difference as one panel can have from the next, or one measurement from the other.

Why do I need to see Rtings links when I’ve seen and measured 55” and 65” screens sizes with my 5nm PR670? My comments are solely based on my measurements, not a regurgitation of another party’s.... no disrespect to Rtings either.

I know. And if you're able to share any measurements, I would be excited to see them.

Sony's sets do appear to be better for color volume, but the extent of the difference is critical, because LG and Panasonic sets have advantages in other major areas. I haven't measured them in person, so the best I have to go on is what's been posted online.

Unfortunately I cannot post them as they are tied to a corporate client. Understood about your measurement limitations. Just keep in mind that the only way an LG OLED can produce 80%+ DCI color volume is when the peak brightness setting is set to Low. When set to High, the color volume is in the 70’s.

A $25k spectrophotometer? With a 5nm spectral resolution? Seems like it ought to be adequate to calibrate home TVs. I wonder whether the people at rtings.com have tools of the same caliber?

You can’t beat the Greens on an LG C9.
