Previously (not me, but otherwise similar. outcome: mount into the brick).
Our twist: the wall is certainly decorative. It's Tuscan course, thin, 18-inch-long brick with a finished band top and bottom above a rustic center.
The logic of drilling the brick is well taken. But as the brick is non-structural, and therefore may even lack form-holding studs behind it, is it even a good idea to try? TV is about 40 inches, a couple years old, and probably between 50 and 70 lbs.
