if software or display plug connector issue is there then it can be solved easily, but if your device get display burn in issue then only possible solution is to change the display

Just try this from your dialpad and check all your Four Colours RGB & Black option...

there are certain apps available on play store to check the burnt display or to fix the dead pixels available on burnt display... some people use these apps to fix the dead pixels but personally I have not checked.. and it is nothing more than this that different different colours are coming for whole display as a screensaver for Some time..

this issues persist since the launch of s9 plus in 2018. sometimes poor video leads to black crush.check if it is also available in high definition video
