My V90 CC 2018 was also set to "06" by default. I tried feeling the difference in warmth between "01" and "09". In my experience "09" does feel warmer but that could also have some sprinkle of placebo since my logic says that higher number should be warmer. I will keep it set at "09" for now and see if I feel any difference in the long term.
