Contemplating buying an LG C4 at Costco with 5 year Allstate warranty for $1600

Hi all. I'm planning on upgrading my 10 year old Vizio 1080p tv to a 4k OLED. I understand that this is going to be a huge upgrade, but I'm wondering if it's worth getting the OLED or a cheaper regular LED. The cost difference is about $1000. I just want to make sure if the price is worth it to go with the OLED. Will I be amazed by the picture with OLED over a standard LED? Just looking for some opinions. Thanks
