      But the graphics you're getting in that case are all the graphics in that
      item, not all the graphics in the selection.




Yes, I know.
So I have to loop thru the items of selection and get allGraphics of item i of selection.

This is a script to switch the display setting of every graphic item of the active spread (if nothing is selected).
If something is selected, it switches the display setting of graphics in selected items only.

 
// SwitchDisplaySetting.jsx  

Object.prototype.isGraphic = function() {      
	switch(this.constructor.name) {      
		case "Image":      
		case "EPS":      
		case "PICT":      
		case "PDF":      
		return true;      
		default :      
		return false;      
	}      
}   

app.displayPerformancePreferences.ignoreLocalSettings = false; 

// all or selection only  
app.selection.length == 0  
	? myObjects = app.layoutWindows[0].activeSpread.pageItems  
	: myObjects = app.selection 

for (oneObject = 0; oneObject < myObjects.length; oneObject++)  
	getGraphics(myObjects[oneObject]) 

// Inventory of graphics  
function getGraphics(theObject){  
	if (!theObject.isGraphic() && theObject.allGraphics.length > 0) {  
		for (oneGraphic = 0; oneGraphic < theObject.allGraphics.length; oneGraphic++)  
			switchDisplaySetting (theObject.allGraphics[oneGraphic])  
	}  
	else if (theObject.isGraphic()) 
		switchDisplaySetting (theObject) 
}  

// switch display setting  
function switchDisplaySetting(theGraph){  
	theGraph.localDisplaySetting == DisplaySettingOptions.highQuality  
		? theGraph.localDisplaySetting = DisplaySettingOptions.typical  
		: theGraph.localDisplaySetting = DisplaySettingOptions.highQuality   
}
