In the early 2000's I restored an EBD LE. The start of a plan to provide pins after Williams closed and before Stern really started making great pins.

I bought a NOS EBD playfield. I had it clear coated by Bill Davis. Over time the artwork under the clear coat was cracking.

Mine was kind of between white and cream colored. I've run into white paints that aren't colorfast so over time they change. Age or UV light.

If it's a reaction in the paint, it all changes. Not just an area.

I had an O Scale model railroad engine painted in Freedom Train colors. Over time the bright white faded to cream color, engine and tender. both sides. And it was sitting on a shelf all the time. So both sides had different exposures.

That reminds me of the Brunswick bicentennial pool balls. I bought 5 sets. Never used them. Stored in the original boxes in the shipping master carton in a dark closet. 25 years later I dug them out. The white parts on all the balls had turned a cream color.
