Do all innovations work in ios 10 on iPhone5?

Question

iPhone

There is a 5th iPhone, on which the second beta of ios 10 is already spinning. In general, there are no big complaints about the work, it’s clear that the beta, and the device is already old. But I could not find some innovations, for example, a smart search in Photos and, in the same place, creating presentations based on an album. Has anyone else dealt with a similar situation?
