Set A Tax Category - Tax implications, differences & comparisons?

Apologies for asking this question here, I'm quite new to all of this. Thank you in advance!

Apple recently released the feature to set a tax category for apps, and it appears that taxes may change based on the category developers set their apps to.

Just wondering if anyone has any information on the tax differences between the category settings, or maybe even a chart to compare?

To clarify, will developers be taxed differently if they set the Tax Category to Books, Games, Artwork, Fitness and health, etc? Will it be more or less tax compared to the default 'App Store Software' Tax Category?

Also curious what happens if a product falls in between the lines? For instance, a pseudo manga-type app that contains features that allows the app to be sent as a Greeting Card, or even serve as a mini-game. Would this app be categorized as Artwork or Books, Greeting Cards, or Games? And how will the taxes change based on how the app us categorized?
