No way to distinguish plant matter from fish. It does however show better bottom detail. Another thing , when waves are created from boats etc. the bottom detail goes up and down like waves. I never had this on my other finders. Maybe someone else with better knowledge on these units will chime in.

FE1 is correct .... DSI will not show fish symbols/arches. Fish will show up as small dots/blotches, but can be made bigger with 455 kHz setting & zoom. The small screen of the Elite 4X DSI will make it even harder to see those "fish" (marks).

As I understand it :
The Elite 4 has 2d sonar & GPS (no DSI)
The Elite 4X has 2d broadband sonar in color (no DSI, no GPS)
The Elite 4X DSI has DSI (no GPS, no 2d sonar)

DSI creates a picture quality image on the screen, in finer detail & smaller pixels than traditional 2d sonar ... so, yes, if the boat is bouncing up & down in the waves, the screen image will show the bottom contour in a wavy pattern, since it's greater detail will pick up the slight difference in depth. It will look something like this :
