The Colorful Future of Displays
Developer Craig Hockenberry argues that since displays are now essentially free of visible pixels, the next frontier is in expanding the number of onscreen colors. For years, computers have supported the sRGB color profile, but the late-2015 iMac and the 9.7-inch iPad Pro support the newer DCI-P3 standard, which displays a wider range of color and is now standard in filmmaking. If you have one of those Apple products, Hockenberry has made a tool to see the difference between sRGB and DCI-P3, with photos by our own Jeff Carlson as examples. However, Hockenberry warns that this transition will make things more complicated for developers, and he advises them to start reading up on how to use color profiles.
It is interesting that people are looking to expand the colours displays can render, but I feel that the benefits are limited. Looking at the diagram for DCI-P3, it seems that half or more of the additional colours are outside the range of the human eye so are not going to improve the colour range perceived by humans. The next version after DCI-P3 still has most of the improvement outside human eye range too. However, there is enough within range that it should be noticeable.
Secondly, having a screen capable of an expanded range may be of limited use if the peripherals do not support the same range. For example, most cameras only produce images using sRGB. And what will happen when printing out DCI-P3 images?
I noticed that in the graph as well, but the difference is apparently still enormous. I guess I'd have to see it in person. (Perhaps a trip to the Apple Store is in my near future.)
You make a good point about existing peripherals. That's why color management will become crucial during the transition.
