Hi Kamil, I have some experience with both versions of Efi RIP but I¹m not sure if can repeat your test in next days... /anyway I don¹t preffer use Efi tools for measure anything :-)

" just curious, how can be measurements soooo different????"

But what is more important, that measurement of light is completely something else than measurement od solid materials and the second and most important thing that your measurement is "colorimetry" (measurement of something virtual what we call "human color perception"). We can imagine it as something similar to music recorded in notes - it looks very uniquely determined but at the end we can get many interpretations of it. It¹s not too big surprise to get different results in interpretation by different apps on different operating system. Calculations in color management depends usually on libraries and other parts in chain. I understand your expectation in versions of application from one vendor Efi... generaly I can recommend only one thing for measurement consistency - use only one tool set (measurement device + application) for continuous compared measurements or archiving.
