Well, yes, and no, and yes. Small camera lenses are probably going to be more evident in certain defects. On the other hand, there are typically less elements in smaller camera lenses, which is nice as the less of those there are, the less the chance of other defects. Taking a picture like mentioned above could absolutely create a 'per-camera/phone' correction profile. May not be able to correct every type of defect but I could see it being useful for some lenses. I know for Sony cameras, there have been a couple models where a large percentage of the copies produced have -one- soft corner.
