This makes me think that maybe mantis shrimp relies on powerful sensor to see the world but doesn't have a lot of good software / internal hardware to do further processing. Human's eye sensor seems poor compare to the ones of mantis shrimp but a lot of work is done in the post processing. It's be difficult to clearly define if mantis shrimp can indeed see "more".
