Here's some pics I took last night, I didn't have my camera handy so I took them with my phone. Here's the dash lights at the dimmest setting.
As you can see it dims quite a bit darker than the handbrake and seat-belt light, luckily the hill-start assist light isn't as bright.
Here's some pictures of it on max brightness for comparison.
The dash gets pretty bright, although this I think forces daytime brightness for the displays which is way to bright for at night. Sorry the pics didn't turn out the best, and obviously this is the Canadian model but I think the only difference is the infotainment screen and the handbrake light, but idk for sure.
