Using area() or $area function in QGIS, when the data (polygonspolygon) is stored in UTM32N (25832)UTM?

I have a question regarding the areaarea() and $area$area function in QGIS and St_Area in PostgisPostGIS. I

I am trying to calculate the exact area of Polygons stored in a Shapefile in UTM 25832 and do not know which functions are the correct ones to use. I know that the difference between areaarea() and $area$area in QGIS 3.10 is that the first is calculated planar and the second with ellipsoid. I

I have also tried to calculate the area with ST_Area in PostgisPostGIS and get the same result as in QGIS with the area function or with ArcMap.

When my data is projected as UTM 32N (EPSG:25832) isn’t it already planar and can be calculated with the simple areaarea() function instead of $area$area? Or do I have to use the $area$area function even if it is in UTM32?
