[RPG] With Truesight do you know that a creature is invisible


Would a creature with Truesight know that the creature they are seeing is Invisible?

I noticed that the See Invisibility spell says "you see invisible creatures and objects as if they were visible" PHB 274. This seems to suggest that everything appears completely normal.

Truesight specifies (PHB, 284). Emphasis is mine.

A creature with truesight can...automatically detect visual illusions and succeed on saving throws against them, and perceives the original form of a shapechanger or a creature that is transformed by magic. Furthermore, the creature can see into the Ethereal plane.

Invisibility is an Illusion spell(PHB, 254), and Truesight automatically detects visual illusions and gives you perception of a creature trasnformed by magic. Therefore, you not only see them, but you've detected the illusion of invisibility or seen the original form of a creature that uses magic of any sort to make them invisible.

For See Invisibility, The rest of the party may also have input

The language remains a bit of an issue for See Invisibility, but as long as there is one more person available to ask 'Hey, you see this?", then they'll confirm the creature is invisible.
