XPS 15-9560 4K, Standard or Premium Panel?

It's actually "Premium Panel Guarantee".  That designation refers to essentially a support policy for the display that means Dell will replace it for smaller issues than they would normally replace displays.  You can read about it here.  The 4K display on the XPS 15 9560 is the upgrade option for that laptop (the base display is 1080p non-touch), but based on the information in the link I provided, it does not appear to be covered by the Premium Panel Guarantee.

I got big Stuck Bright Pixels and look like it was burn on my Screen, do I have to sent back for replacement?

Assuming Dell agrees to replace it under warranty, if you did not purchase a warranty that includes on-site service, then yes you would.

Thank you for your message. I will be glad to assist you with this.

Has there been any accidental damage like the system being dropped or anything heavy placed on the lid?

Restart the computer & tap F2 to get into BIOS screen & check if the issue persists.

What is a Dell Service Tag and how do I locate it?

I get this problem since I open it box. That time it was just a bright stuck pixel. But after I keep it and never get feedback from my Dell Local Authority, it becomes big day by day. They force me to keep it when I bought it. But I was decided to bring my Laptop back to them since October. The System never dropped or collision. Service tag is #
