Yikes... Novus on the front polarizer surface of an LCD is not going to do anything good. At best you will remove the anti glare coating on that area leaving a shiny spot as Vid mentions. If you go deeper hitting the TAC you could damage the polarizer itself causing new artifacts, color etc. One option is to laminate the full surface of the display with a new film (think mylar). The adhesive should wet out the scratch and then the whole surface will be the same "texture"... Likely glossy. Think screen protector for cell phone but more of a pain in the ass.
The best and only realistic option is full replacement as you are getting. Or of course trying to ignore the scratch.
