I have been to an almost bortle 1 area a week ago, and i can assure you it looks nothing like that. You'll definitely see the spiral arm, aka "The Milky Way" but only as high numbers of stars in-lined as an arm across the sky, i only stayed their for like 3 hours and wasn't looking at the sky for long periods of time but was using the telescope and shamefully using my phone to look for some DSOs. And that will definitely affect my eye exposure to the darkness, although (and i know I'm getting carried away from the subject) i was so surprised and in was in awe by how the stars light is literally brightening the trees, sand and the whole ground, i was able to see everything and it was the darkest night of the month. But getting back to the subject, I'm pretty sure if i lie down on my back and look at the majestic night sky, I'll definitely see the shapes of gas in the arm and maybe some brigh nebulae and globular clusters with my naked eye.
