Researchers increased temperatures at the test plots by 3.4 degrees C, an increase that might happen by the end of the 21st century, and learned that plants grown and measured at those
higher temperatures increased their leaf respiration by an average 5
percent, compared to plants in
ambient temperatures.
Had the juvenile plants not been acclimated to the
higher temperatures, their respiration would have increased by 23
percent over the plants in
ambient temperatures.
So in addition to washed out, under saturated and distorted colors (red tomatoes, fire trucks, and Coke cans look a bit orange rather than deep red, for example) it continues with a moderately
high screen Reflectance of 6.5
percent, almost triple that of its favored littermate, which further washes out its image colors in
ambient light...
On the other hand, the iPad mini 3 lacks the anti-reflection coating and has an air gap beneath the cover glass, which results in a moderately
high screen Reflectance of 6.5 percent, almost triple that of iPad Air 2, so its Contrast Rating for High Ambient Light is 61, which further washes out its image colors in ambient ligh

High Ambient Light with Automatic Brightness.
Compared to the 4th generation, the screen reflectance decreased by 23
percent, the peak brightness increased by 7
percent, and the contrast rating for
high ambient light increased by 32
percent — all good.
As discussed below, the record low screen Reflectance of 4.7
percent for the Galaxy Tab S further improves its effective Screen Brightness in
high Ambient Light.
On the plus side, the iPhone 5 has a much
higher Peak Brightness (556 versus 421 to 491 cd / m2), a much lower Screen Reflectance (4.5 versus 5.6 to 6.5
