docs: Return the display values.
  
          Return the current (possibly uncalculated) display values unless 'immediate' is specified.
  
          If 'immediate', return the existing (calculated) values if they exist. Using the 'immediate' values
          avoids calculation except in cases where the display values haven't already been calculated.
