Suppose when you live in Iceland or other similar latitudes, and the sun starts to appear on the horizon, the preferred seating is the sun side to see hours long sunrise / sunset

That's a big assumption that the sun can even be seen lol it's always cloudy here in SE Canada it seems. It's nearly 8am the sun supposedly is up but the clouds are so thick it may as well be 5am.

SE Canada is like France, though. We’re talking Iceland here, which is way north compared

Oh I know Iceland is about the same as northern Labrador or even south east Nunavut. But here in SE Canada especially Newfoundland the warm Gulfstream and Labrador current both meet here so it can be quite foggy. Plus it seems we are like the tailpipe of North America every weather system seems to end up here even hurricanes.

More like there are two modes: no Sun or sunlight directly in your eyes.

I get the same result[1], and I'd have expected that if I still live in the Arctic, but I'm a lot further south and see the sun out the window right now.
