When streaming Dolby Vision content, either with an Apple TV 4K (3rd generation) or using the television’s own Apple TV and Netflix apps, the A95L picture had horrific banding and posterization in some scenes.
In low light shots, the picture becomes seriously desaturated and takes on a green tint. Sony’s processing also adds undesirable sharpening that cannot be disabled and the media player never worked for us. The Samsung S90C QD-OLED we replaced it with has other shortcomings, but it never suffers from over-sharpening, horrible banding artifacts and posterization.

I assume you disabled all of the TV’s default processing setups per input before testing, that kind of poor performance seems a bit OTT.
The behavior I saw was identical to that experienced by Classy Tech Calibrations on YT as well as by countless others over at the AVS forums, who shared their own screenshots showing banding and posterization.
