Here is a 3D overlay on the Lab color space:
So it seems that the K2 is actually overall brighter on the luminosity scale. But the relative contrast between K1 & K2 are close enough(maybe a slight edge to the K1) that they're very similar. |
Excellent info. I suspect that given the potential issues with scanned images, the representation is close enough to give a good look at the two displays.

Just read each axis then you can figure out what each plot represents. The vertical axis is the "luminosity" (or what most of us consider brightness.) Then the two other axises are for color shift or shade. One is for the yellow-blue and the other for red-green (at least that is how I am reading them). Where the plots show for each display will give an indication of the perceived color of the display. The way the graph is laid out, the effective contrast would seem to be the difference between the two plots for each device.
As
shinew describes both devices have almost the same relative contrast ratio. The K2 seems to be just slightly brighter which could make some fonts or images appear to be a tad faded to some people. And the data bears out that some people find the K1 to seem a tad dim even though there is the same contrast ratio.
The "color" shift of the display of one device might help one person see the text well and cause problems for others...still others will find it just right.
No matter if I did not read it quite right, the info from the plots is just what I had been expecting from the data I have read elsewhere. As well as anecdotal/subjective commentary about the display of the K2 relative to the K1.
BTW, I am assuming the top two plot points are for the background and the bottom two are for the text?
