It doesn’t really matter. All curved lenses cause barrel distortion - just not the “fun house” extreme of a fisheye.
As you can see in the screenshot above, the horizon appears concave (which i think we all - except the minority, concavers - agree is NEVER the case in reality - regardless of altitude). This is caused by barrel distortion and is due to the focal point (dead center) of the lens being pointed below the visible horizon.
Please let me know if you have any questions, or are at all interested in the greater subject.
