Camera [Q] Any way to disable the brightness boost in the Sense 5 camera?

It's pretty annoying that the camera ignores your brightness setting while open. It's a terrible drain on battery; I often prefer to minimize my brightness while shooting to get the most longevity out of the device but this doesn't seem possible on the One.

I'm aware that other camera apps don't have the same issue, but I'd rather use the Sense camera.
