actually a big issue with them is to get them to proper default values, because they are also included in some emissive stuff like here the tvs at Brno:

With setting sun they become really dark:

and then if the tracklights going on they became bright and thats what does not really fit into a real logic, because why should they have the "backlight" off while day:

So if they would have the backlight on also while day, it would work:

So all the problems come from the "old" AC too dim daylight logic where night and day were having the same brightness to be able to use a static exposure. But now with Pure you could think like in reality. So at day you need more power to view such LED screens.
