iOS 18.2 Profile Pictures in Mail Missing

I noticed this when I first updated to iOS 18.2 when it was initially released: the marketing materials for the new mail app show that the new icons have profile pictures. (see image below). We have these boring profile pictureless symbols that don't say much. (see image) Will we get the profile pictures shown off in Apple's marketing materials, and if so, when will they be shown?
