The work shown in the pictures is pretty typical. Indeed, I've seen many far worse.

The little wire wraps are, despite appearances, not like springs. They are simply there to give a firm connection to the box. At that task, they succeed, resulting in a good, tight grounding connection by the screw, and little stress on the cover plate. Folding plastic 'caterpillars' are made, and sold, by electrical suppliers for this very task.

Also sold are plastic forms that slip into the box, and are a listed means of filling the gap between the box and the device. That brick may not burn .... but usually the painter will pack the gap with caulk, or mud - and the plastic forms also keep the gunk out of the boxes.

A similar problem arises when tiles are laid after the boxes are set. Here you have another problem; cutting tile isn't exactly a precise craft. Nor has the tile setter much reference as to the size of the plaster ears, etc.

Sometimes you're left with lemons - and all you can do is hope to make lemonade from them.
