You can see them on solved mysteries and on all maps where the have a green ok symbol
It in not corrected on gc.com that are displayd but caches with coordinates in persional cache note. This i becuse ther exist no API metods to get all corrected coordinates but ther exist one to get all user notes. the only way to detect a corrected on gc.com is to donwnload that cache as that user.
To verify that persoan cache note and corrected on gc.com i would recomend using GSAK
It check that you have coordinates on gc.com require a download of that cache and you only have 6000 full and 10000 light per day(and for that reason pgc will problily never detect them if no new API is addev my groundspeek). The information that the cache is corrected is not included in pq(atlest GSAK cant detect it)
To validate that the corrected are in cache not you have to download all possible caches and check for corrected cordinates. If you like to do that i would recomend to do that i GSAK You can use macros to add that ot the personal cache not on gc.com.
To check if caches with corrdinates in personal cache not have correctet corectad cordinates on gc.com is not as hard. because you can get the gc codes oth the caches fomr the Solved mysteries map on pgc.com. A refesh and som filter will idetify problem in GSAK
