The Z9F is the successor to the Z9D. The performance is somewhere in between VA-type TVs and IPS-type TVs. The contrast ratio is fairly low, so blacks do appear gray when viewed in a completely dark room.
The TV has local dimming to mitigate this dark scene performance though, and it works well. When viewed in a bright room the TV can get exceptionally bright to overcome glare or produce bright highlights in HDR. The Z9F has low input lag and an excellent fast response time which is great for gamers.
Model tested: 65” (XBR65Z9F)
Should also be valid for the 75" (XBR75Z9F)
