Can't see how but my mate has got away with black and silver pressed plates on a 2008 for years
Probably hasn't gone abroad into Wales! I did thousands of miles on my black and white black plates in England without issue. Went across the border and within 30 minutes got pulled over. Copper only did it cause he was annoyed he didn't get to book me for speeding as I sailed past him and his gun at exactly 30 miles per hour. He had a good walk check around the rest of the car to see what else he could try to book me for but as I keep my car in good knick he found nothing. Did thousands of miles after that back in England again never had an issue.
