Regarding the aesthetic score

I'm curious about the aesthetic score.

On the Understanding AI scores help page it says "this score combines various scores (purely aesthetics, composition, technical) to infer a global score that is used in Panorama".

But what exactly is the aesthetic element, and what parameters is the evaluation based on? As aesthetics is a rather wide area, a more concrete and specific explanation could be useful.

Best regards,
