Do I need to be worried about burn in with the 48'' UltraGear™ UHD OLED Monitor with Anti-Glare Low Reflection 0.1ms R/T 120Hz and G-SYNC® Compatible?

I recently just made a purchase of this monitor. And I am worried about burn in? Is this something I need to worry about or it becoming less common? I never used an Oled gaming monitor before but I got it so I can run my 4090 on it.
