The past few years have seen a dramatic improvement in display technology. First it was the upgrade to higher-resolution screens, starting with mobile devices and then desktops and laptops. Web developers had to understand high-DPI and know how to implement page designs that used this extra resolution. The next revolutionary improvement in displays is happening now: better color reproduction. Here I’ll explain what that means, and how you, the Web developer, can detect such displays and provide a better experience for your users.

This will seem a hassle until multiple profiles can be included in one image. I can see only photographers caring for this in the meantime. But it’s great that this is finally coming to the web.
