Possible gap in camera bar?

Never noticed this on any other phone I've owned. A few minutes of holding my 9 Pro XL next to my AC vent and condensation built up under the camera glass.

It went away after it warmed back up, but I tried the same thing on my work Pixel 8 Pro holding it closer to the vent longer and nothing showed up.

Just seeing if this is happening with anyone else's or if I need to warranty exchange it.
