Why isn't the Earth perfectly round in the photos? Simple, it isn't. The Earth's equatorial diameter is 12,756 km, while the polar diameter is 12,714 km. There is also a slight bulge (about 45 m) in Northern Hemisphere, making it slightly pear-shaped.
I don't think that would be enough to be visible, at least not with the photos of the size he's displaying. You're talking about a 0.3% difference between polar and equatorial diameter.
