Pressure marks on 2015 Blade 14 QHD

Hi, I just bought a used Blade 14 laptop ( model RZ09-01301E21 ) and the center of the screen has some white / black marks depending on the angle. At first I thought it may have something to do with the illuminated logo on the back as the marks are in the same area but while searching how to disable it, ( it seems like it's not possible on this model ) I found out that these are most probably pressure marks which need disassembling the screen to be removed. I found some tutorials to fix this issue but not on how disassembling the screen on this particular laptop. I'm a noob but hopefully if I find detailed instructions about how to take the screen assembly apart I would be able to repair it. I don't want to pay for repair as this is an old laptop I got for super cheap so I will either try to fix it myself or leave it like that. Thanks in advance for your help
