Very cool to know. These kinds of stats can be incredibly useful to those whose use cases depend on color accuracy. However we should be careful about a few things:

- Unless something's changed, this display is Diamond PenTile RG/BG. This detracts from the integrity of the resolution specification of 2960x1440. The display contains only RG or only BG in every other denoted pixel, instead of RGB in every pixel. This puts the effective sharpness around what true 2093x1018 (mult by sqrt(1/2) to account for least common dot type) to 2417x1176 (mult by sqrt(2/3) to account for total dot count difference regardless of type) displays might have, but with a slightly grainier appearance if you look closely enough, and with slightly higher demand from the hardware. It can be misleading to consumers when companies produce/use displays like this and don't make the difference clear to consumers. Because they usually don't, it's especially important for us to take on that duty when writing articles about these products. Remember that comparisons of brightness and power usage should be done against other displays of similar effective sharpness, not against displays of the same denoted resolution spec but which may be true RGB matrix.

- 3K doesn't seem like the right term for even true 2960x1440. If you compute it based on ratios, with 4K being 3840x2160, then 3K should be 2880x1620 as it was in the Thinkpad T540-T560 3K models. 2960x1440 has larger width but smaller height, and 8% fewer total pixel cells. It's important to recognize when companies are repurposing pre-existing or mathematically well-established resolution terminology, and reflect that in the articles that we write.

- Know the difference between colorspace coverage and colorspace volume, and reflect it when writing articles. Colorspace volume can exceed 100%, but that doesn't necessarily mean the whole colorspace is actually covered -- it could be a weird shape that exceeds it in some hues and falls short in others. Colorspace coverage cannot exceed 100%, but when it's 100% you know it covers all of the particular space in question.

DisplayMate had a lot of good things to say about the newly launched Samsung Galaxy S9's display. The firm says that the Galaxy S9's OLED display sets new performance records that makes it better than most high-end displays available across form factors and gives it an all time high A+ rating.
