stand at the edge significantly.

Because the display of the Lumia 920 at the edge slightly arched, the films are about 3 mm from the edge. This not only looks very unsightly but annoying enormously if one roams eternally fingers over the edges over time.

Since the heavy-handed attempt by Mr. adjuster helps very little of the claims that this is intentional.
From the film from a reputable manufacturer, I expect bond strength also on the sides.
