Live photo editing no apple standard app

I have a lot of Live Photos where the first few frames are not great but the middle section is perfect.

now am I wrong in thinking apple made a really big deal of he love photo giving the impression you could edit the picture to the frame you want to get the best outcome of your shot?

after hunting about I have found an app called live edit on the AppStore but nothing from apple.
Im really pissed off that there's no standard way to get a stil from a live photo without having to use a 3rd party app.

so am I missing something or what?
