My guess is that the main reason many devices have reflective stock screens is that a reflective screen has higher brightness, while a matte screen is dimmer. I think most will agree that matte is preferable in actual use, but when looking at basic screen benchmarks or when looking at a bunch of screens in a hardware store, buyers are attracted to bright screens.
This is great, I actually had no idea that existed! Very glad I asked the question now.
How well do they work compared to displays that are already matte by default? Is it basically the same thing or would it introduce some imperfections?
There could be differences in protector quality as well, I've no idea about that.

Sad that there is no option for matte 4K+
I bought my Precision 5750 in late 2020 so my infos might be outdated. Check the description or call a Dell rep.

Writing this from a X1 Gen9, I wouldn't call the following "very good". Not sure if it's already fixed in new firmware (and couldn't google the support forum right away), but I had to
* switch sleep mode to stop it from getting hot while asleep;
* disable touchpad in BIOS to stop it from spinning fans while awake — great for me because I don't like it anyway and vastly prefer the trackpoint, but people not used to this consistently go wtf while trying to show something on my laptop.
Never had the touchpad issue though.
