Yes, you would be able to see more details, but those details progress relatively to the main quality slider and the resolution itself. If there isn't enough space available to render the detail a quality of 2 or even 3 won't help you.
Those super-low scale details won't even be noticeable if you decide to print the picture in 20x30 cm format, so I prefer to not pump-up the detail too much on bigger renders.
I would have to do some test-renders someday and put them on the wiki for public use.
