Usually cameras produce output-referred images, i.e. they in-camera processing already converts the captured image to say sRGB viewing conditions, so that the images look "nice" when displayed on a monitor. I.e. we get say sRGB images out of the camera and only need to care about converting from sRGB viewing conditions to the viewing conditions of our desired viewing environment (e.g. reflective print, monitor in bright or dim room, projector in dark room) - there is no need anymore to care about the viewing conditions of the captured scene, since the camera already did it.
I am not shure about that. The mentioned example with dark scenes shows me very high contrast and saturated images which certainly do not match my visual impression. So at least my Canon camera appears more scene referred.

Raw images are a different issue - here IMO the raw converter would need to account for the viewing conditions of the captured scene (where the viewing conditions may be estimated e.g. from the EXIF data, as you say). Regards, Gerhard
