I wouldn't be surprised if Ami's HUD did have a night vision mode at about the modern MILSPEC level of effectiveness. The Silver Millennium items they get from the mooncats seem to be at about a 2010-2015 level of technology, like the communication devices. Video chat phones would have been cool as hell in the mid 1990s, but now they actually exist. And the same with netbook-sized microcomputers, although the power of Ami's isn't given -- it probably calculates at the speed of plot anyway.
