It looks like the standard pre-cut PPF template. The installer looks to have done an OK job joining the lines of the template itself. Pros of having all these relief cuts is the film is less stretched and less likely to lift in high tension areas. Cons are the relief cuts creates edges that can catch dirt/debris and make the lines look more obvious, and will leave some parts of the paint fully exposed.
A better installer would edit the template to fit their abilities. I have less faith in clear PPF applied to a car with no relief cuts at all to hold up long-term; unless we start seeing owners post photos 6+ months afterwards to show otherwise.
