But then Boeing states this

RANGE 787-8 7,355 nmi (13,620 km) 787-9 7,635 nmi (14,140 km) 787-10 6,430 nmi (11,910 km)
Pick and choose your favorite Boeing page (Wikipedia uses the second Boeing page)
Suspect if you dig into the details, the assumed passenger load or cargo or some other factor is slightly different
