What makes you think UV vision would give tetrachromatism? Most common real-world equivalents just give an extended blue band (old-fashioned film cameras were UV sensitive, and normally used UV coatings or filters to cut it out, because the major effect is to make landscape shots hazy. Electronic cameras probably do the same, as would human eyes if the cornea didn't block UV). In any case, it's not completely useless, it's just that it's mildly useful and mildly harmful, which adds up to zero.
