Apparent FOV is not bullshit, but a standard measurement usually given in a optic spec sheet.
IF you don't like that, then look instead at the FOV in degrees, this thing is said to have a 12 (!!!) degree FOV, like holy crap! THAT's HUGE! I would suspect though that in order to boost it that large that their is noticeable barrel/pin cushion distortion towards the outer edges of the image...
