Base S23

My phone is 2 months old

I turn off my phone every night to minimize overnight drain, and ive even heard its good for the phone

but yesterday and today ive noticed when i turn on my phone that there is a faint samsung logo in my walpapper, it goes away after like 4 seconds

i dont know if this was there before or what, maybe i havent notice it

BUT - Will screen retention lead to screen burn in? Or should i stop worrying about this
