What features do you consider essential for something to be proper Detective Vision?
For me I think the ability to see enemies behind walls would definitely be one, but there needs to be more. I considered "highlighting mundane objects the player may or may not be able to see without the DV on, but are only interactable with the vision enabled", however I think this would rule out a game like The Last of Us where the iconic Listen Mode only shows you enemies through walls.
From a Wolverine clip I just watched, his Feral Vision highlights enemies, but NOT through walls so I wouldn't count it.
