I had the 24" 1920x1200 Apple Cinema Display for several years, and I vividly remember that text looked objectively worse after I upgraded from Mavericks to Yosemite.

I now use a 27" 1440p monitor and I'm always struck by how bad text looks on it compared to my 2009 MBP that's stuck on Mavericks until it dies (not due to text reasons, it's just slow as hell/no benefits to upgrading).

They did something that was relevant to 1x displays, because it used to be better.
