The 4K bluray of Mad Max is about the most perfect film for Atmos and HDR combo. The sound design is off the charts amazing. Now, for the questions that your question generated: By "bipolar" do you really mean "dipole", or should you possibly be talking to someone more professionally qualified to look into your issues?
. Could you mean "bi-amped"? Odd that you would have dipole towers up front, but even more odd that you would have bi-amped surrounds. Also, you say "surround back" that are in-ceiling, and then you're getting two more in-ceiling speakers "in front of back row" to get to 7.1.2, but you have two subs, so that would be 7.2.2 or is it really 7.2.4? I think you need to study the Dolby white sheet and possibly reorganize your layout to better accommodate the full effect of Atmos. Some adjustments may do wonders after you have a look.
