storage internal sd

on the samsung galaxy A3 2017:
when you have moved an app to the sd card:the storage indicated in the app settings indicates an sd storage but not all the files of the app are moved to the sd card.it seems only the apk files are moved to the sd card.
does this mean the storage indicated (namely sd storage) is only a part of the application?
some smartphone indicate 2 parts:
device storage and sd storage

I've read that on the galaxy S7 you can move the whole app to the SD card not only a part of it.Is that also the case with the galaxy A3 2017?

I'm wrong it's only if you use sd card as internal memory you can move the whole app to sd card.
