Whether that's the case or not, depends on the reason for being lean. Vacuum leaks tend to do that. Vacuum leaks can be variable depending on what else is going on.
I can imagine a few mechanisms that could be going on, but no point speculating on such limited information. If it is really important to figure out, you either need to get a system engineer looking at it, or become one yourself.

To a certain point lean flames are hotter, the average cutting torch shows that. If you go super lean then yes it cools, and that is how the TC-18 aircraft engine could obtain such a good BSFC.
