Since you know the product (frame.work) well: how does one get the specifications page?!
Last time I checked, they (notebookcheck.net) said it used a glossy display instead of matte; I cannot find a specifications table in the frame.work website and the closest thing I got is in the "Marketplace Parts" section, e.g. at https://frame.work/products/display-kit - where the non-trivial, simply critical detail of glossy vs matte is not specified.
Sometimes the display is so closed to the keyboard when closed that adding any layer is going to damage the display. Macs are good example, you can regularly see keyboard imprints on the display even when there are no additional layers.
It's very hard to do that without any bubbles and a real built in layer is closer to the pixels so there's less blurring. I don't think that's a great alternative for a factory matte screen.
I stick with Lenovo because they make great displays with matte that can even do touch!
Unfortunately, proper placement of a matte film is far from trivial. Nor is procurement.
I used a firm that provided an excellent product and decent service, but two years ago they replaced the film they had used for many years and which was superb, with an appalling grater - you can see the pins with naked eye, and it even sounds when you pass a finger on it. I have stopped purchasing mobile devices because of lack of proper ways to finish the screen.
I was actually thinking of finding a "universal" solution to use at home.
For laptop displays, I think will insist that they are professional grade, for professional use, until () the "universal" solution is in place and () for ethical reasons: you have to guide the market to the best standards and counter the bad ones.
Update: as I was just now searching for information about some equipment to keep at home to make (these too overly frequent) glossy displays matte,
I met from a most prominent producer of chemical products the statement
> Glossy Protection Film offers a glossy finish to help maintain the finish of a glossy display or instantly upgrade a matte display to high-gloss
Repeat for disambiguation: they would """upgrade""" matte to, mh, glossy and highly so. There was also a picture for the monstrosity nearby. So, that «isn't possible» has a counterexample. (Which is not difficult: rub some oil on it etc.)
When I saw that further confirmation of the apparent ongoing process of the total eclipse of good sense and downfall of ethics for the perverse purpose of courting lunatic rubes for their wallets, I uttered something along the lines of Sean Lock's "Are you mental?!" (from the cab driver asked if free for giving a tiger a night ride) - only, in a discriminatory form that moderators would not approve.
I know it's a joke, but the point of glossy displays isn't being glossy. It's that they let more light through without distortion, which means more brightness and better color accuracy.
The matte layer already damages the light. A glossy film can only make things worse.
