How much of Earth we can see at once depends on our distance from the Earth. The closer we are to the surface of the Earth, then the smaller part of the Earth we can see at once. Conversely, the farther we are from the Earth, more of the Earth are visible to us.
The difference in the size of North America in these pictures relative to the size of the Earth is often presented as “evidence” that we have been lied to. In reality, it is simply a perspective effect. The pictures are taken from a different distance from the Earth and with a different camera field of view.
