Same here. Owning a Q9FN (2018), top of the line TV discounted price at $2999 at the time of purchase, brand new from Samsung. I thought I can get the best of the best, NOT! Atmosphere brightness feature terrible. Local dimming is almost a killer for the TV. dark features can't be seem. Have to turn these feature to off or lowest of lowest settings so I don't get the spotlight on/off effect watching movies. Dark screen is dark alright. I can't even see anything in the dark area of the scene. (played with multiple backlight/contrast/HDR+ settings) finally turning every features off and it got slightly better. And now, Netflix UltraHD TV shows. only shows only HDR instead of Dolby Vision, no Dolby Atmos, nothing. My Brother got a LG at 1/3 the price, it's got everything! AND AND, it looks better. Don't believe me? Go watch Umbrella Academy, Altered Carbon on Netflix. Samsung Q9FN, and LG (forgot the model, but it cost <1/3 price, (think it was only around $700 vs my Samsung $3000.) and everything looks and sound better. No spot light effect for local dimming. What have I done.... Only reason owning this TV is 36 month 0% interest free TD bank account. Going to have to get rid of this TV and get a real TV that support the popular standards without all the SW bugs.

My mistake of getting a "top of the line" TV expecting supporting everything possibly out there. HDR+ or HDR10+ is a different story, most people can't see the difference for the color is already brilliant enough.
However Dolby Atmos is a significant sound improvement to the sound field. To not support it is just bad reputation.
Besides a bunch of FW defect on local dimming, ambiance light sensing...etc. after numberious FW updates, this TV still performs sub-par comparing with my LG that cost 1/3 the price.......
