'Additional content' list to enable A/B check?

This is probably just my lack of understanding; which is that LPX 10.2.4’s ‘Show Available Downloads’ in the left hand side Library indicates automatically where any missing Content exists which may yet be download-able. And so far after checking maybe 20% (so not all!) of the patches they all seem to work. Why is it then that when I review the files in Library / Application Support / Logic / ESX Factory samples / Legacy instruments …. I see folders numbered 1,2,5,7,8,9,11,27…etc … i.e….it would SEEM there are still lots of folders (files) missing.

On another related issue, I never FEEL like I really know whether I have all the Content I should have, and LPX too often tells me I don’t. OK, so one goes to Sound Library Manager and downloads whatever is indicated … BUT… it does;t always download .. and it is not just me, there is plenty of discussion on the forums (though mostly older) indicating others have similar issues… SOOOOO… is there a ‘Contents list’ for Apple Additional Content available to us so we can simply A/B the issue?

thanks and regards
