Help with caddx ant aio

Hey guys the caddx ant supposedly has a 145° fov but when I got another camera with 150° I realised the caddx ant aio only has maybe 100°, does anyone know why? Or what camera it actually is in caddx ant aio package? Doesn't look like an ant?
I'm looking for a lower fov fpv camera but I don't know what fov I have been flying with. Thanks
