is there any Function to extract all the view modes for specific node? Is there any function which can give you all the types of view modes available for specific node? 
Also is there any direct(UI) way to check it ?

Is going to edit->manage_display the only way to get the view modes ?
The code below will give me the list of view modes

$entity_info = entity_get_info('node');
$list_of_view_nodes = array_keys($entity_info['view modes']);
