Is the 85-inch worth double the price of the 55-inch?

Only if you sit 10 feet or more from the screen. The panel technology is the same, so you are paying for size, not a better picture per inch.

Which is better for gaming?

Both run 144Hz native with VRR and Auto Game Mode. The 85-inch lists Game Accelerator 288 versus 240 on the 55-inch, a small edge for high frame-rate consoles and PCs.

Which has better sound?

The 55-inch lists a 40W ONKYO 2.1 system; the 85-inch lists 20W. Both have a built-in subwoofer and Dolby Atmos, but either benefits from a soundbar in a large room.

Do both handle bright rooms well?

Yes. Both use QD-Mini LED with up to 500 dimming zones and high HDR brightness. The 85-inch adds a matte panel finish that cuts reflections.

How far back should I sit from each?

About 6 to 9 feet suits the 55-inch. The 85-inch wants roughly 10 to 13 feet for a comfortable 4K image.
