I can't find anything that even implies this is possible, so I think your best bet may be to look at Field Messages (show the value you want underneath the actual).

Unfortunately, That's not possible to have different display set for a table on different form. One table can have one display value set and that field will be visible every where you referenced to that table. 

You can try below in field attribute (in field dictionary) to populate multiple values when search in lookup field but the display will always be the value is set for display true.
