The article incorrectly states, "In contrast to other manufacturers such as Dell or HP, Lenovo does not offer any option to modify the color space or color profile. So as long as you work in the AdobeRGB color space, everything is okay, but as soon as you work with sRGB files, there are some high color deviations".
Lenovo supplies the Intel Graphics Control Panel software, which allows for custom color profiles. As-is, due to the high Adobe RGB coverage, the HDR panel is often color-over-saturated with non-color-managed applications like the web, video-streaming etc. I was easily able to set up a custom profile for non-color-managed sources, although it does take a little trial-and-error. I saved the original, calibrated profile for Photoshop. But you're right, it would be preferable for Lenovo to provide such profiles or explain the availability of the software, which is easy to use without a colorimeter for this purpose.
