Should I buy Aero 15 ?

Hi guys I am thinking to buy new Aero 15 with rtx 3000 series and I need help in few concerns!!
First, I wonder if it is risky to buy Oled version because I heard that it may get burn ins over time,change in quality or picture retention .. have anybody face this issue before? especially aero owners more than 3 years before now ..

Secondly, I may sometimes work(programming) in cafes or public places and I also seen some revies talk about the fan noise will that be a too loud to use it in public places!!

Please Give me your feedback guys
