Harry Potter and the Cursed Child US and UK Edition Difference

The original Harry Potter series has its UK and US editions be very different. But what is it with the Cursed Child? There is only one real difference, and it is very slight. Very, very slight. Take a look at the two covers. The only real difference here is that the UK cover's logo for Harry Potter and the Cursed Child is a few pinks thinner than the US that shifted to the original American logos that appeared in the American editions and the films.
