I can see it being played (and even intended) that way: seeing an invisible creature is better than, well, not seeing it, but hitting or defending against Predator-esque shimmering target is still hard.
It's a 2nd level spell, a significant resource, especially at lower levels. It's VERY niche; if it doesn't work as advertised that's a big bummer for the player. It's literally the one thing the spell does.
It also SAYS you see invisible things as if they were visible. Not as some shimmering blurry thing. A player should have some warning if a DM will use this interpretation.
