Does the Samsung QN55QN85DBF support Dolby Vision?

No. It supports HDR10+ and standard HDR10, but not Dolby Vision. If Dolby Vision content matters to you, look at other brands.

Is this TV good for gaming?

Yes. It has four HDMI ports, one with eARC, and supports 4K at 120Hz with low input lag, which suits PS5 and Xbox Series X.

What size is the screen and can it be wall-mounted?

It is a 55-inch flat panel and is VESA-mount compatible, so a standard wall bracket will work.

Does it have Alexa built in?

Yes. Amazon Alexa voice control is built into the TV through Tizen, so no separate Echo device is required for basic voice commands.

How many HDMI ports does it have?

Four HDMI inputs, one of which supports eARC for a soundbar or receiver. There is also an optical S/PDIF output.

Is Wi-Fi 6 supported?

No. The TV uses Wi-Fi 5 (802.11ac), which is fine for 4K streaming but not the newer standard.
