I'm not a super serious home theater guy, I enjoy great sound but don't really keep up with the newest stuff. 90% of my tv time is spent on movies or commercial free series, either Netflix or Fios. Very rarely do I watch BluRay anymore, I don't buy movies and renting them has become a pain with kids.
Friday night I updated the 4K Apple TV to TVos 12. When it finished updating a splash screen appears telling you what's new. I was surprised to see Dolby ATMOS was highlighted. I searched Netflix for ATMOS and the results were slim. I put on Lost in Space and the receiver auto switched to ATMOS and locked out other formats. Within minutes I knew ATMOS is NOT for night time viewing if you have family sleeping! Voice volume is much lower compared to other formats so you turn up the volume to hear them, then BOOOOOOM something collides on screen and the whole room shakes. I'm sure there are better ways to watch movies and stuff, but I'm pretty happy Apple added ATMOS.
As far as Dolby Vision...I can see the screen and it looks good - my eyes just don't care.
