yup - once you've done your taxes, it will be reconciled the same as FTB and CCB. provided estimates have been accurate all year, you'll get the 7.5% back
if you've overestimated your income, you will get a CCB top up, which will reduce your CCR by half that amount (so if you get $100 of CCB, $50 of your CCR from that 7.5% will be kept)

does that make sense
