My paint should I be worried?

Was it always like that and you recently noticed?

I would try some polish next. My last car was white, and it would get strange yellow stains during the summer randomly. Polishing was the only way to remove them regardless of how often/recently it was waxed.

Also, you may want to provide some different photos in different light so others can see if it's a clear coat vs base coat issue. Your camera is going to underexpose on purpose since it's white paint, so add 2/3rds of a stop/brighten it first before posting.
