Unless the spray can coincidentally stopped spraying paint just as it got to the "three o’clock" side of the circle, it looks very much as if the graffiti artist went out of his (or her) way to protect the bricks from getting paint splashed on it, perhaps by taping off the area before spraying. This care is important because it’s easy to repaint a garage door and "notoriously difficult" to get spray paint off of a porous surface such as brick.

Likewise, the encircled "A" on the left side also has a completely vertical stripe on its "nine o’clock" side, which again looks as if someone held up a barrier to ensure that no paint got on the bricks:

When you think of your average Antifa type (these mug shots may be representative), does that Antifa guy or gal strike you as the kind of person who would carefully avoid getting any paint on bricks so as to spare Pelosi the inconvenience of getting the paint off the bricks?

It’s entirely possible that this was an Antifa effort and the person spraying paint had some residual compassion for Pelosi. But it’s also possible that this is a false flag effort. I am not offering any suggestions as to who might have raised this false flag. I note only what others have pointed out before: Something’s peculiar here.
