No we just did a comparison between Redshift with no tuning, conservative tuning, aggressive tuning. The point was just to assess "how much does tuning matter anyway?"
You are correct that if we wanted to do a full-on "tuned comparison", we would need to implement partitioned tables in BQ, Snowflake and Presto.
