So is this operation something that you can visually inspect? In other words, should I be able to see some movement of the mount itself when the engine RPM increases above the 900 rpm threshold, or during start-up or shut down?

Haven't tried so couldn't say. I would think it would be difficult to visually inspect and see any difference as I could not tell there was any issue until comparing side by side. Check out the link below for more info, specifically cm335d attached images to get an idea of what a collapsed mount would look like.
