in the magic land where suddenly you had mantis shrimp vision and everything else being equal you’d probably just see stuff more or less the same, but probably wouldn’t be able to see coherent information from screens as they are designed to work with human (and recently by proxy) mammalian eyesight (i still don’t think cats and dogs can parse images from CRT displays but they seem to do just fine with LCDs, but that’s just anecdotal… like my entire comment)
