First you'd have to find a TV without Dolby Vision....
I mean seriously, I purposely bought TV's with Dolby Vision when I upgraded my Apple TV's last time. And they are several years old now. And they weren't expensive TVs.
I can't imagine this is very useful to many.
It really needs to be more specific:
You can have a Dolby Vision TV, just not watching Dolby Vision content. The reason for this is DV has it's own profile that handles the color settings. IIRC, the only thing you can actually change with DV is the backlight settings.
