I'm in the same camp. The supposed blue light/sleep correlation was briefly in the news about 10-15 years ago, and even then it felt like it was as much woo-woo "science" as the paleo diet. Since then, pretty much any blue light study I've read has been focused on risks to our vision. My ophthalmologist has been recommending blue light filters for my glasses for a few years now, and I can confidently say that they've helped a lot with screen fatigue. But that's a physical filter, not a display color filter. For those, in my opinion the main reason to use one is because you like the color gradient better.
