As for that manual extra update: it's not instant; the staff member basically just creates a task and puts it in a queue. It should only be requested if the automatic update is stuck and hasn't happened in a couple of days; this manual update restarts the daily cycle. I wouldn't get my hopes up for more than once a day in the future.

If all your images have the same category or use the same template, you could use DPL to list all File pages that don't use a certain category or template.
