It’s a bit more than that, the highline has a ecu in it, it also deactivated differently, and can give you more camera angles, but the bit you’ll see would just be the 2 bendy lines. Plus the camera doesn’t switch off as soon as you take it out of reverse, it carries on to 5 mph (which is a pain in the arse if you have the parking display (forgot what it’s called) and front sensors), but yeah I have a highline set up as a lowline
