なんか画面が白っぽいなあと思ったら、LG製ディスプレイを搭載している場合にそうなるらしく。
If you have a newer MacBook Air you should pay attention. Some of the MacBook Airs are shipping with Samsung displays, and some are shipping with LG displays, both are quality displays, but the LG's default color profile is lighter and a bit flat. Most users probably won't notice this, but if you sit a MacBook Air with a Samsung display next to one with the LG display, you can see the difference. This is easily remedied by using a custom color profile that has better gamma. This post will walk you through how to check which manufacturers panel you have, and also show you how to add a custom color profile that makes the LG display just as gorgeous as the Samsung.
確かめたらまさにLGのディスプレイだったので、上記サイトからカスタムiccを頂いて見違えるように明るさや発色が変わった。
（追記）購入後しばらくすると明るさや発色が変わってくるもので、3週間経過した今は初期のプロファイルのほうが綺麗なような気がする。
