Is there a difference in 7.1.4 processing

I am building a home theater area in my basement and decided on 7.1.4 (or 7.2.4). I am starting to develop a short list for a receiver and am looking at the Yamaha RX-A3070 but in their manual they only show 7.2.4 support using the front presence speakers instead of top speakers...I have wired for four top speakers. So my question is, with the processing of the Atmos signals be different for front and rear presence speakers vs top front and rear speakers? I'm wondering if I should scratch Yamaha off my short list.
