Now you need to return that Sony 950 and save some money, and get a much better tv. Go buy the tcl 8 series mini led. You’ll thank me, hdmi 2.1 is pointless anyway. Yamaha 3080 is hdmi 2.0b and so is all your other stuff. Hdmi 2.1 will change to hdmi 2.1a with a different hdcp to make everyone start over once again. Get the best tv you can afford right now. No such thing as future proofing in this hobby.
Also the Yamaha 3080 was a great choice. manual peq far exceeds denons capabilities. Also it’s more reliable and runs much cooler. Great choice on canton, I own 596.2, 556.2, 896.2, 866.2, 518, 515 and many in ceiling and in wall as well. Now don’t skimp on amps or subs. The canton love power and really need it for high spl. The 596.2 system almost made my denon 6700 burn to the ground, but denon run extremely hot.
