Sometimes, it is difficult to visualize the gap between sensor measurements merely by looking at a spec sheet. The photograph here may give you a clearer sense of the sensor dimensions in the HZ25W and A7S III.

Clearly, both of those cameras come with the identical megapixel count but different sensor measurements. The HZ25W offers the tinier sensor which is going to make achieving shallow DOF more difficult. The older HZ25W is going to be disadvantaged in sensor innovation.
