If the ad is just blacked over, it is still loaded, and they wouldn’t know.
If it became a common thing, they’d have to add detection for it. Not necessarily to stop people doing it, but to ensure advertisers aren’t charged for invalid impressions.

If they were effectively able to detect it they would be able to block you watching the rest of the video.
