Yep, this is the traditional three-coat. What’s interesting is the framing need not be perfect. You can correct a quarter inch off true across a wall without too much trouble by varying the thickness of the brown and scratch coat. In my old house the framing way way out of wack and the drywall would have visible bends if forced to adhere to it. Making the final wall true when dealing with imperfect framing is done with the dot and screed method. You can also add dyes into the finish coat and leave it unpainted. Shame plaster has died out for most construction.
