thanks to Gene and the Audioholics YouTube videos I finally realize I'm not crazy, and Atmos can be very underwhelming compared to other formats like Neural or Dolby Surround. I thought there was something wrong with my system when Atmos content would rarely put sound in my front height speakers, and when it did, it's pretty faint/quick. I would just assume change my Apple 4K TV box streaming format off of "best quality/Atmos" and upmix in my Denon 1600 receiver to Dolby Surround or Neural that makes use of the height speakers. But before I do, is there some other benefit to the Atmos/object based sound format other than a signal occasionally going to the height (or ceiling for those that have those) speakers? As in, are the ground speakers (front L/R, rear surrounds, center) getting a different kind of mix with this object based format vs. just using Dolby Surround, Neural, or other formats? Kinda feeling duped by the Atmos hype, although I know all I have is front height speakers above the front L/R (5.1.2) so perhaps without in-ceiling it's not worth the bother.
