Usually, it is hard to visualise the gap between sensor measurements just by reading specs. The visual below will help offer you a clearer sense of the sensor measurements in the DP2 and A7S III.
All in all, both cameras posses different megapixels and different sensor measurements. The DP2 using its tinier sensor will make getting shallower depth of field harder and the Sony A7S III will offer you greater detail having an extra 7MP. Greater resolution will also enable you to crop pics somewhat more aggressively. The older DP2 is going to be behind in sensor innovation.
