This reduced overall image quality and caused pixel-fine details, such as small text, to appear smeary on high-density LCDs. In contrast, well-designed glossy displays provide a superior visual experience by minimizing internal refraction and reflecting ambient light at high angles, which reduces display pollution. Consequently, glossy screens often appear much brighter, blacks appear blacker without being washed out, colors show a higher dynamic range, and small details remain crisper. High-quality glass glossy displays are often easy to use even in full daylight, and reflections are manageable because they are full optical reflections with correct depth, allowing the user to focus on the screen content.
Apple's "nano texture" matte screens were engineered to solve the specific optical problems of traditional matte finishes, the washed-out colors and smeary details. But they cost more to make. The glossy option is still available, and still good.
When your screen can do 1,600 nits, daylight isn't as much of a problem
To get to actual 1600 nits you need to use scripts.

Not sure the impacts to display health or battery running the screen full bore like this.
I'd much rather do that than to have a granier screen with worse viewing angles all the time I'm not in direct sunlight, so next time around I'll be back on glossy.
