What screen are you looking at it on? There are all sorts of colour grading styles, often it does go through trends but punchy images are still very common, and I’m not sure what you’re talking about with yellow ones…

Look at the picture of the dog: some of its fur is overexposed, and you can’t get the values back. A logarithmic scale means you lose less detail at the extremes (bright and dark), so the log picture isn’t overexposed.

I think the question was more about the general tendency to make movies with that teal/orange look, that's still going on strong after 12 years.
