Help My screen is Burnt!

Hello
I am new to this site, as I hope to find a logical solution for my situation
I have a G900f S5, I recently started to notice that my phone's screen is not as white and bright as other galaxy phones its yellowish, when I deep looked into my screen while its on I was able to see a fade of my lock screen and the keyboard ( on a white screen) if anyone is facing this problem and found a solution or even a logical answer please help me.
Thanks:)
 
If so What caused it?

Static image. This is a known issue in OLED panels. You aren't supposed to leave static images on your screen for too long otherwise the LED units can get dimmer over time. If you leave your screen on for hours with one image, then the image can get burned in. This is mostly due to the user. I've had a Galaxy Note 2 for 4 years and has no screen burn in that I can see. However color degradation is a bit noticeable. Depending on manufacturer, lifespan of AMOLEDs nowadays are between 20000-40000 hours of screen on time. However, since you have an older phone, it can be shorter than that. Back in 2010, commercial AMOLEDs only lasted for 10000hours. As each LED is lit up, it degrades. So if an area of the screen is always on more than the others, it will degrade faster, thus losing color, which is called burn in.

Shorter display lifespan is what you pay for the pretty image. Typically the display would last fine for the two years they expect you to keep the phone. When you reach 2 years anyway, it should be expected that the phone doesn't look like new.
 
The blue LEDs have a shorter lifetime than the red and green, which could explain your colour shift to "warmer" colours.

(I out quotes around "warm" because the nomenclature for colour temperature always bothers me: cooler sources produce reddish light and really hot ones produce blueish, but we call a red bias warm and a blue one cold...).
 
Super LCD is way more reliable, I have some phones from 2012/2013 with Super LCD and the screens are still like new today.

My old Galaxy S was the SLCD version, and yes the screen held up better over time. But we only have ourselves to blame for wanting our phones to get slimmer, since OLED panels can be half as thin as LCD panels.

I'm not too picky about my phone's height, my current phone is 8mm high with removable battery and IPS panel, I'm happy with it [emoji6]
