Dell xps 15 9560 4k

Hi,

This is an odd question but anyway I will soon be buying an xps 15 4k version and I wanted to know what the black levels are like because I have been watching videos of the laptop and to me it almost looks like dell uses oled tech the blacks are that black!

But this can't be the case...

In short; can owners of the xps 15 9560 4k version please tell me what the black levels are like?

Thanks in advance!
