A YouTube video is likely a single track of audio or a very minimal amount. A movie mixed for Dolby Atmos is designed for multiple speakers. Now, they will create compromised mixes for something like a stereo setup, and a good set of bookshelf speakers will be able to create a phantom center channel. However, having a dedicated center channel speaker will do a much better job. And using the TV's built in speakers will do a very poor job. Professional mixing is a different beast than most YouTube videos, and accordingly, the sound is mixed quite different.

Yup, I definitely do agree those are wildly different beasts. But the end result is, the professional mixing is less enjoyable than amateur-ish youtube mixing. Which is a shame, really. Mixing is a craft that is getting ruined (imho) by the direction to perform theatrical mixes (where having building-shaking sfx is not an issue) or atmos mixes (leaving no budget/time for plain stereo mixes).

The crux of the issue IMHO is the theatrical mixes. Yes I can tune the TV volume way up and hear the dialogue pretty well. In exchange, any music or sfx is guaranteed to wake the neighbors (I live in a flat, so neighbors are on the other side of the wall/floor/ceiling).

As someone with a dedicated center speaker, people doing audio mixing do not effectively use it. I even have it manually boosted. Sometimes it's 10% better than without one, but nowhere near enough to make a real difference.
