Yeah it’s not great, the high resolution camera is great in the day, not so much at night. I don’t know there are easy solutions, supposedly the reverse lamps are filament bulbs, I’m not so sure though, at least in my S60, all the lighting is LED.

Anyways if you are handy and willing to take it on, I installed a couple reverse light “spotlights” next to the license plate lights above the plate area next to the camera. Not a hard thing to do, other than I got a sedan, I tapped into the reverse light wires going to the tail lamp, but needed to run the wires into the trunk lid. No big deal for me to do though. Solved the problem, plenty of lighting now to improve the camera view in reverse.
