Correct.
To use upgrade points, you need W fare or higher. W is rarely available on 858. Often it's H or E or M.
I have never seen K on this route. If you buy S, then you need to pay fee plus points to upgrade.
1K is almost guaranteed to get upgraded.
Nothing is free here. If you are not 1K or Plat you don't have upgrade points.
