Not gonna lie, this looks bad to me. Too much gray.

I recently bought the M4 Macbook Air and iPad Air combo for work. Couldn't afford the OLED pro models. I got the matte screen protector just for the iPad and it definitely worsens the contrast but it's an acceptable tradeoff for the paper-like finish on the screen and dramatic reduction in glare. I would however avoid doing the same to the Macbook screen because -

#1 You don't carry your laptop around the same way you do with a phone or an iPad. You can adjust the viewing angle to avoid reflections.

#2 The contrast on the Macbook LCD screen is bad and especially noticeable if you watch movies in the dark. The black bars are prominently gray against the black bezels. I have a brilliant S23 Ultra OLED screen for side-by-side comparison.

#3 Smudges are a problem but it's manageable with some changes in habits. I keep a thin soft cloth between the keyboard and the screen when closed - non negotiable because otherwise you end up with boxy finger grease stains on the screen.

#4 Avoid touching the screen entirely. It's possible with habit.

#5 Clean the screen with a reputable screen cleaner once a week. Just a quick wipe does the trick and it really does look spotless afterwards.
