Further note that if you add --color, you can see the difference:

$ ls -Fd --color=always / // | od -tc
0000000 033   [   0   m 033   [   3   8   ;   5   ;   2   7   m   / 033
0000020   [   0   m   /  \n 033   [   3   8   ;   5   ;   2   7   m   /
0000040   / 033   [   0   m   /  \n
0000047

The file name you typed is colored, while the trailing / indicator added
by -F is not colored.
