I’m skeptical. Yea the images might look a bit different, but this could be due to colorization making it easier to see snow vs dirt and grass. The zoom on one of the images isn’t the same, you can’t just zoom on the one area that has glacier and crop out the rest of the water, and wide angles make everything look more dramatic. In real life it could just be a few acres. I’ve taken photos in small lakes that look like massive oceans, with barely a shoreline in sight.
