For the "default" column I left the Note 2 in its out-of-the-box settings, aside from disabling auto-brightness and cranking the brightness sliders to max (I did the same for the iPhone). For the Note's "adjusted" column I made those two changes: engaging Movie and unchecking AAST. Brightness, black level, and contrastIf the Note 2's adjusted screen has a comparative weakness, it's still limited light output. The iPhone can get more than twice as bright, which means it will produce better picture quality and be more legible than the Note 2 in very bright lighting like sunlight or direct indoor light.
On the other hand, at full brightness the Note 2 can get nearly 50 times darker than the iPhone 5, In a completely dark room, like the one in which I measured the phones, a black (0 percent stimulus) test pattern filling the screen of the Note was barely visible; the same pattern on the iPhone was much brighter, The difference was less obvious, although still visible, under normal apple - iphone 7 smart battery case - black lighting, Contrast ratio is the difference between the brightest image a display can create and the darkest, According to my measurements in a completely dark room, the Note 2 offers roughly 20 times as much contrast as the iPhone..
In a dark environment, the better contrast of the Samsung's screen will cause its image to look punchier, especially with high-contrast material like dark scenes in a movie or a nighttime photo. Under normal room lighting or brighter, particularly a daytime sky, that advantage will dwindle and the brighter screen of the iPhone will shine through, overcoming ambient light to provide a more legible, clearer image for all types of material. I originally wrote the above for the Galaxy S3 comparison, and it's basically the same here. Yes, the Note 2 can get brighter when it's adjusted properly..but so can the S3. The smaller Galaxy also has an AAST control that bumps its light output to about 233 nits -- roughly the same as the Note 2.
Color accuracyHere's where it gets more interesting, When you engage apple - iphone 7 smart battery case - black the different screen modes, colors go from garish (Standard) to exceedingly accurate (Movie), If you're wondering, Dynamic was even worse than Standard and Natural roughly split the difference between Movie and Standard, When I turned to my trusty photo montage (thanks to Lori Grunin) the improvement was significant, A shot of various skin tones looked much more natural in Movie than Standard, which punched up reds and made flesh look too flush, Bright flowers and fruit also looked realistic in Movie as opposed to candy-coated in Standard..
Comparing Movie on the Note 2 to the colors on the iPhone, the iPhone still looked a bit better, with a touch more saturation and vitality. One visible difference between the two was in their grayscales; the iPhone tended toward a bluish cast while Movie on the Note was more green, differences that became more visible in more black-and-white images. I also think Movie might make gamma a bit shallower and washed-out than the iPhone's ideal 2.2, but I didn't measure gamma for this comparison. As always it comes down to personal preference. Some viewers might like the over-saturated look of Standard or even Dynamic, while some might stray toward Natural or Movie. I think it's great that the Note 2 provides a choice, especially since different material can call for different modes.
