I'm confused about the High Frame Rate. My current Apple TV I have set to 60hz and Dolby Vision. My new Sony supports Dolby Vision as well but up to 120hz. Been using the TV's native apps and native AppleTV app to get that in the meantime but have been looking forward to switching back to AppleTV box once the new one comes out which most all presumed would have 120hz. Saw it mention high refresh rate and since it already has 60hz, I assumed they meant as expected 120hz, but don't see it anywhere on the specs. What am I missing?
