All of the non-iOS displays are calibrated via a munki.
The MBA display from this generation (my kids have the 11” MBAs with basically the same crap display) is the worst I’ve used by far. So bad it’s basically useless for photo editing. The contrast stinks. The color gamut stinks. You can’t look at it off-axis at all.
No no, I’ve looked at a lot of displays in my life. It’s my least favorite. The 2009 13” MBP display was better.
That there are non-Apple laptop displays that are even worse is cold comfort.
