Nissan Y62 Dash

Hi I am completely new to the forum. I have possession of my new Y62 which is now four months old. I have noticed a mark on the dash which is spreading. Today (24/02/2025) I took my Patrol into my local Nissan dealer and showed them the marks. The service person who viewed the vehicle said it was my fault. That I must have spilled something on the dash, and that it would not be covered under warranty. We explained that the only thing we had done was to wipe the dash with Armorall. So my question is has anyone else had a mark like this appear on their dash?
