The question is legitimate though as sometimes we do get 3D renders, e.g. when it comes to this image of the Korolev crater on Mars: https://www.esa.int/var/esa/storage/images/esa_multimedia/im...

They even added the fog (the fog in the picture is white and while there is dust on mars it's rather brown as the planet's surface https://mars.nasa.gov/imgs/mep/weather/PIA22520-600.jpg ).
