A:AnswerThe issue is eARC not ARC. "Enhanced" ARC is not persistent on devices that have eARC when connected to this TV. I have 2 of the exact same TVs and both have the same issue. Use the latest Apple TV 4K that has eARC and connect that to the TV's eARC HDMI port and you will see that the eARC connection will be lost and only ARC will work.
A:AnswerCy - The QN95B comes with a 2.5 meter One Invisible Connection cable, as well as a 0.3 meter to use when you attach the Slim One Connect Box to the back of the TV. A 5m cable (Model: VG-SOCA05/ZA) is sold separately as an optional accessory.

A:AnswerDoggy - The length of the screws varies depending on the thickness of the wall mounting bracket and if spacers and/or washers are being used. The thread pitch, regardless of TV size, is always 1.25 millimeters.

A:AnswerWall mounting is always an extra for TVs as far as I know. This one comes with a center-mounted, very solid, functional stand and the "one connect" box that goes behind it.
A:AnswerThe 95B has the new "neural" networks for its AI not the 90B's "neo" networks. Shape adaptive lighting for better blooming control. HDRX 32 vs the Q90B's HDR24X. Symphony sound that incorporates the sets speakers with your sound bar for a fuller sound. Also more than a few nice options in the various menus that are not vital but are nice to have around. One such option is the above mentioned symphony sound mode but you can also choose to simply output volume from your soundbar or receiver and the TV's speakers together and adjust the setup to your liking. Oh and the 95B has external rear speakers as well with a higher output wattage than the 90B. Owning both I find myself a bit bummed with 90B but in no way unhappy with it overall. It's just ever so slightly less polished and less feature full. There is only a negligible picture difference and it only shows during particularly difficult scenes for the sets to display.
