During advent events, only N, bronze and silver mats will increase. I've tested using a MLB anzu with a support sleipnir, anzu or vlad, D'Art with snatch 2nd and Mammon for 3 events, casting snatch on every enemy in rounds 1 and 2, and using all 3 snatches twice on the boss. In the end, the increase was 5-7%. It saves a few battles when the rewards you want require a majority of non-gold mats. Reduced elemental boost from the eidos and reducing damage in order to cast snatch often offsets time saving, so It's best to use them in a way that doesn't slow you down too much.
Not sure if this is correct but in this video he state that Item drop% also increase the gold chest rate in sp quest and have a good amount of sample.

Also the snatch icoin is platium chest so is will be quite sarcastic if it only increase the amount of bronze and silver chests. Maybe the amount of gold chest is already too lower than the other 2 so it'll be hardly to noticed.
