15 pro max screen was repaired today but the max brightness setting is not what is used to be. Repair was not done at an authorized apple repair shop but the replacement screen is an original OLED (at least that’s what I was told).

After the repair, I noticed a new message on my settings regarding an unknown part.

Will updating to the newest OS solve this issues and restore brightness to what it should be (up to 2000 nits)?

I work outdoors and depend on having a very bright screen. Please help!
