It's also not been stated outright. The anime adaptation of events has so many contradictions it's clear that it's entirely non-canon The manga states he gave Ashura power and leadership of Ninshu. Depictions of Ashura afterwards shows him using powers similar to SPSM and TSB and Hag said his mistake was giving one son everything and then divided his literal power equally between Sasuke and Naruto.

Giving Ashura SPSM/at the very least 6 Paths Chakra would only upgrade the power he already had, so he wouldn't have all/absolute power.
