Both night vision modes need SOME light to operate. Take your bottom comparison. The Cam Pan shows there is a faint light in the room (probably blackout curtains in the afternoon). The Pan V2 takes that faint light and makes a very nice picture, showing the effectiveness of the starlight sensor.
In the top picture there is no generalized faint light. Just the glow of cracks, or night lights behind furniture. Whereas those areas are lit, the room is not. Since the starlight sensor is not sensitive to the IR lights being on without being in night vision, it has no light to work with.
The very top picture is night vision on with the IR lights on. Turn the IR lights off, and it will be as dark as the second pic (maybe darker).
Both need SOME general light to work. For most people a yard light can provide enough light. Without the yard light you are at the mercy of the clouds and the moon phase, and without a cloudless full moon you will probably be disappointed.
In your situation, I’d use the settings of the top picture. Standard night vision with the IR lights turned on. I don’t know an easy way to put something is that room that would just glow a little in visible light without being a minor distraction to someone sleeping there.
