Dolby Vision is hardly a "killer upgrade".
Unless you watch your television in a completely dark, cinema-like room, many/most Dolby Vision titles are unwatchable. Take a show like Ozark, on Netflix. This show's cinematography as a "style" is already shot very dark. If you switch on the Dolby Vision, the dark areas can't be seen. It's a complete waste of time. In many cases, people not only turn "OFF" the Dolby Vision, but turn on the enhanced brightness on the TV's in order to see what's going on.
Dolby Vision is worthless for home viewing, and Dolby Atmos is useless for home listening.
