Auto-exposure on maybe?

I think not, I can't see it on my screenshot.

It's not important today for me but weird

This is likely normal: it's the modelling of the camera inner workings, and if it is so, it's also analogous to the real world counterparts.
If you think it's not, please share a scene and some more info.

See this thread- Specifically this post explains it:

It's mimicking the behavior of a lens focusing close, where there is more light falloff when the lens gets farther from the film plane.

yep, as the real world sample in the docs i linked above.
As it's now possible to just screenshot and paste, here:

But the thread provides info on how to prevent this behavior if you wish, and explains why this behavior occurs, and how it is calculated. The docs are a little thin on details.

You're right.
