The fees that you pay stay the same, but a part of the fees is refunded in the form of a vesting balance. Small fees vest immediately, higher fees take 90 days for vesting. Once the fees have vested you can withdraw them (note that withdrawing also costs a fee).
To see your vesting balances, go to your "Account" tab on openledger, then click on "vesting balances" at the bottom left. Vesting balances are recalculated hourly, so you might not yet see any.
In the cli the command is
