readability of your iPhone. Is iPhone 6 brighter than iPhone 5?

I like it (pro version). The authoritative tests on the iPhone 5 vs. 6 indicate that the 6 might be very slightly brighter. But the 6 and particularly the 6 plus have a larger (and much larger) display, which contributes to readability.
