Turned off the "feature" as soon as Tv was on. Have been advising friends and adjusting their expensive oled TV's as well. In every case they were grateful for me "fixing" their TVs which only took a few minutes.

People just don't want to muddle around in the settings. And here lies the problem. It would be great if manufacturers would open up their interface settings to be influenced more easily by mediaplayers or settup boxes. Those in turn, could have a ruleset: if 24p, then disable motion blur if else enable motion blur. If sports enable motion blur. And so on.

It's not even limited to motion blur, I have low light and normal light profiles I'd like to have changed automatically based on the actual light in my room.

Motion smoothing is designed to reduce motion blur. It doesn't always work, because it's just heuristic processing that attempts to estimate the missing information, but when the motion is easily predictable (pans are an obvious case), and the exposure time (shutter angle) is low, it can do an excellent job of interpolating the missing frames. This eliminates the sample-and-hold blur[0] that would otherwise appear. It's motion sharpening, not motion blur.

[0] Blur Busters has a good introduction, that's relevant to all non-flickering displays, not just OLED: https://www.blurbusters.com/faq/oled-motion-blur/

I work in the lighting control industry. Your final paragraph piques my interest. I’m curious, why automatically change the TV if you could automatically change the room? Shades drop, light intensity lowers, CCT warms, etc...?

Most people aren't exclusively using their TV to watch movies. When turning on the TV in the afternoon to watch your favorite soap opera with finest motion smoothing, you might not bother that much and just want the TV to be a little brighter.

Fair enough. Wonder if any SmartTVs have an API endpoint for brightness/profiles. It’d be cool to have an external/remote ambient light sensor that could change your TV setting automatically.

Because the vast majority of people don't have multi-thousand dollar room control setups but they would find some benefit from their entertainment devices being able to describe their features to each other.

Yes, cost is always a factor. That said, if the room control was affordable, would changing the space be an objectively better solution than changing the display?

I think ultimately you probably want both, because sometimes you (... or at least I) have different wants around viewing. Sometimes I'm going for a cinematic experience, where I want the room dark and all focus on the media. Other times I want to be half watching something while playing a board game or doing some cleaning. Optimal lighting conditions for these scenarios clearly differ, and probably optimal display settings to match.

Sensible defaults, oh where did I heard that from?
