I don't know about changing shape but certainly changing shape requires
a change in dimension somewhere. However, I just finished reading an
article that says the common belief that the sun or moon becomes larger
as they approach the horizon has been declared an optical illusion after
being disproven by careful measurement with thodolites.
Well there you go. My eyes and brain are subject to optical illusions.
Your E3 is not yet still images an oblate spheroid. As I said: "I
don't know". :-)

You should believe. The horizontal field of view in this portrait image
(300mm on 4/3 sensor) is 2.5 degrees. The angular diameter of the moon
averages about 0.5 degrees but this super moon should measure about 0.58
degrees. Measure and compare on your screen. The image is real. I think
there's some distortion in the image (from what I don't know) since the moon
clearly shows as an oblate spheroid. But measuring either width or height
is close enough to 5:1 to say that this is the real thing.
The distortion is atmospheric. It is not uncommon for the sun or moon
to change shape as it is close to the horizon.
