Sounds like a screen problem indeed.But before doing a screen replacement,take a quick step and connect the laptop to an external monitor using the HDMI or the thunderbolt in case you have a compatible screen.IF the external monitor works fine after time then it's the screen ready to be trashed.If you have a similar problem something is wrong with the logic board or the graphics card chip in the board.

Just in case,test the connecting cable of the internal screen for loose connection.Open and close partially the lid and rotate-carefully-the laptop to see if there is any similar problem of decolorization.

If all the above indicate nothing,then you can be sure that your screen in guilty!

Hope it helps,
