Yesterday, I was in a tech store and used one of their Ipad Pro 12.9-inch to play around with Procreate. I wanted to zoom in close on the drawing that I was doodling, and it looked very pixilated! I haven't experienced this when drawing in the Notes app at home on my iPad Air. I know Procreate isn't vector based, but I'd just assume it would have looked blurry up close instead of pixilated.
