I think this works with all sort of leather except suede and nubuck I believe.

Read post 197, this TPF member used the kiwi zanolin cleaner on her lambskin, so i'm guessing it should do fine on your smoother leather bag. Give it a try!!!, I would suggest to test on areas that aren't that noticeable and let it dry overnight and see if you like the result.
I heard the apple brand is too harsh on leather bag, i read hit and miss about this product... So I wouldn't risk it
