Drywall is a master of disguise. The walls in this picture look like they could be plaster. One of the visual giveaways that you're actually looking at drywall is when you see the sharp corners created by standard corner bead.
Corner bead is a metal or plastic piece that covers the outside corners of drywall to protect them from damage. Then joint compound is spread over the bead and sanded smooth.
In many traditional plaster applications, a rounded piece of wood trim was placed at the corners and then plastered over, creating a round corner. To mimic this look with drywall, look for a bullnose corner bead.
