[ AnandTech ] Ryan Smith & Joshua Ho:
As with the iPhone 6, both the iPhone 6s and 6s Plus use dual domain pixels, which make the subpixels look more like chevrons under a microscope. This improves viewing angles by reducing the amount of color shifting that occurs when the display viewing angle is changed. As far as I can tell, Apple continues to be one of the few OEMs that pulls this off effectively. Although contrast and luminance aren’t perfectly consistent with changes in viewing angles, it basically looks like the display is painted underneath the glass. The iPhone 6s Plus does a better job at pulling off this illusion as the higher pixel density helps to eliminate some of the fuzziness or pixilation that might otherwise occur.
I consider color accuracy very important because I’d like the photos I take to look as close to the real thing as possible.
The Samsung Galaxy Note 4 in Basic screen mode produces detailed photos with extremely accurate colors. There are two areas where the Note 4 falls a little short of excellent. One is with red colors: reds are slightly washed out and sometimes appear to verge on orange. The other is lag. The Note 4 makes me wait a little bit before I can review the photo.
If you’re using an iPhone 6s or 6s Plus for any remotely color-critical work like viewing and/or editing photos and videos, it’s a pretty fair bet that you’ll be able to rely on these phones to provide an accurate color reproduction in pretty much any condition.
