MacBook Pro 13' 2019 screen - weird colors and flickering?

Hello,

I have no idea how to call my issue properly so I am sorry for my messy explanation of what is happening. Some time ago I discovered that screen of my 2019 MacBook Pro does something weird with the brightness - in a split second it turns down and up and back to normal. It does it very subtle so I can barely notice it. At first I thought that maybe that's the way TrueTone works but after switching it off and auto-brightness off as well I noticed that it still does it. Because my warranty expired I decided not to do anything with it since it was very small issue (if any).

Last time I decided to update to Ventura so I erased my drive and installed clean copy on the MacBook. I just wanted to get rid of all small settings that I could change over the years and now it does something funky. So now I have factory settings (I've only changed dock look, etc) and the screen still does it! I have noticed another issue with the screen and this is the thing I cannot call properly. Pictures or videos are like blurry on bright/light areas. Please see attached screen from my iPhone and photo of the MacBook screen to see what I mean. Look at the face, it is very pink, like contrast-less with a smudge.

How to talk with the service about it? What is it?
