Below is the conclusion:

The Sony A7S III leverages a lot of tech from the A7 and A7R models, and its stills credentials are impressive…Although it puts in a strong performance at its lowest ISO settings, with a relatively high maximum dynamic range and maximum color sensitivity, evidently some concessions were made in that regard, as it is at high ISOs where it’s class-leading. In particular, the Sony A7S III sensor has an impressive response between ISO 1600 and ISO 6400, even outperforming rivals using 24 MP BSI CMOS sensors...”
