If you have oped out, as in your case and mine, the answer is none of your information will be used in this way. It's one setting, it's a complete opt out and you get prominently asked at install time. I've really not got any problem with that.
I don't want any advertising in the software I buy.

Do you? I know the iOS setup wizard asks for analytics, but I don't recall it ever asking whether you want to turn on "limit ad tracking".
"Advertising in Apple Apps: View the information used by Apple to deliver more relevant ads to you in Apple News, Stocks and the iOS App Store. Your personal data is not provided to third parties."
Apparently, you will see ads in their newest apps: News and Stocks apps (and ads for other apps in App Store).
