I mean in this gif (look at the black spots on the moon surface). From left to right it's the same look as if pushing a flat coin on a table from left to right.

The distance the moon actually is from the Earth, this is a sliver of it's horizontal movement. Like 3 degrees or smaller.
Remember the moon is 238,900 miles away from the Earth, so imagine the moon traveling another 30 earth-widths in each direction.
It's a five hour time lapse, and with that camera angle of view you're not going to see much moon rotation.

Truth. Would man have wanted to go there so badly if we saw the dark side? Doubtful.

It takes 648 hours for the moon to rotate on its axis.

From our perspective (earth) it is not rotating, but from other planets or the sun it is.
Imagine if the moon did rotate from our perspective, we'd prob be all dead in matter of hours.

Holy shit. That is so unfamiliar that it looks fake to me. But I guess it is real.
it's called perspective

Good point, why??? is it a camera setting like Field of View or something....
It's just perspective. Remember the satellite is a million miles from Earth taking a telescopic image of the Earth while the Moon (which is much smaller than the planet) passes in front of it.

Crazy fake looking, but cool.

Telephoto lens effect. The camera is a million miles away.
From the article "Combining three images taken about 30 seconds apart as the moon moves produces a slight but noticeable camera artifact on the right side of the moon. Because the moon has moved in relation to the Earth between the time the first (red) and last (green) exposures were made, a thin green offset appears on the right side of the moon when the three exposures are combined. This natural lunar movement also produces a slight red and blue offset on the left side of the moon in these unaltered images."

That's the green channel overlapping the edge of the Moon. The natural color image was built up using different exposures taken close together :
Its a result of imperfectly matching up the exposures.
The moon looks close because this is an image from a million miles away taken with a 30cm telescope.
Why would it even be fake anyway? If you believe that the images of the Earth from this satellite are real and if you believe that the moon is real then its inevitable that the moon at times passes between the satellite and the earth. What would be the need to fake it?

Is that a hurricane? I didn't even know there were any active ones around yet.
It does, doesn't it?

Beautiful. I love stuff like this. I hope I get to employee the universe sometime in my lifetime.

They can't fake anything properly without Kubrick.
Do you ever wonder why the sun looks as small as the moon
Or why the moon is as large as a dime

The dark side of the moon :O
Cool shot.
Cool shot.

Yep, like it was said earlier, it's all about perspective and camera angle. Here's my rough Space Engine simulation of earthrise:
and here's my rough approximation of the DSCOVR image:
Note the extremely narrow camera angle in the bottom right, and the distance indicated from earth.
Yep even if you include Pluto.
