My experience with the 13 Pro has been that heat dissipation on a sunny day is a challenge. The black screen seems to absorb all the sun's energy and the phone quickly has to go into lower power mode (e.g. dim the screen). So, the use case for the brighter screen is only useful if you are planning to use your phone in the shade.
