My new ThinkPad arrived this week and it is working well! The Fedora 25 installation was easy and all of the hardware was recognized immediately.
However, there was a downside. The display looked washed out and had a strange tint. It seemed to be more pale than the previous ThinkPad. The default ICC profile in GNOME didn’t help much.
There’s a helpful review over at NotebookCheck that has a link to an ICC profile generated from a 4th generation ThinkPad X1 Carbon. This profile was marginally better than GNOME’s default, but it still looked a bit more washed out than what it should be.
I picked up a ColorMunki Display and went through a fast calibration in GNOME’s Color Manager. The low quality run finished in under 10 minutes and the improvement was definitely noticeable. Colors look much deeper and less washed out. The display looks very similar to the previous generation ThinkPad X1 Carbon.
