\activatestep is used only on first activation anyway.

For this purpose, you should hook into \displaystep:

\newcommand{\mydisplay}[1]
{%
  {%
    \ifthenelse{\boolean{firstactivation}}
    {\color{blue}{\Huge\Pisymbol{pzd}{42}}\bfseries}
    {{\Huge\color{yellow}\Pisymbol{pzd}{51}}}%
    #1%
  }%
}

\stepwise[\let\hidestepcontents=\hidedimmed\let\displaystepcontents=\mydisplay]
{%
  \step{test}

  \step{foo}

  \step{bar}
}

But I find this a bit too `dynamic': Things are jumping around
badly. What about

\newcommand{\mydisplay}[1]
{%
  {%
    \ifthenelse{\boolean{firstactivation}}
    
{\color{blue}{\leavevmode\vphantom{\Huge\Pisymbol{pzd}{51}}\Huge\Pisymbol{pzd}{4
2}}\bfseries}
    
{\makebox[\widthof{\Huge\Pisymbol{pzd}{42}}]{\Huge\color{yellow}\Pisymbol{pzd}{5
1}}}%
    #1%
  }%
}

\newcommand{\myhide}{\leavevmode\vphantom{\Huge\Pisymbol{pzd}{51}}\phantom{\Huge
\Pisymbol{pzd}{42}}\hidedimmed}

\stepwise[\let\hidestepcontents=\myhide\let\displaystepcontents=\mydisplay]

Looks a bit jumbled, for sure...

Probably one could do this a bit more systematic ;-)

Maybe like this:

\def\mystep
{%
  \switch
  
{\def\labelitemi{\vphantom{\Huge\Pisymbol{pzd}{51}}}\mdseries\dimcolors\color{te
xtcolor}}
  {%
    \ifthenelse{\boolean{firstactivation}}
    
{\def\labelitemi{\vphantom{\Huge\Pisymbol{pzd}{51}}\color{blue}\Huge\Pisymbol{pz
d}{42}}\bfseries}
    {\def\labelitemi{\Huge\color{yellow}\Pisymbol{pzd}{51}}}%
  }%
}%

\newenvironment{stepitemize}
{%
  \begin{itemize}
    \let\origitem=\item
    \renewcommand{\item}{\mystep\origitem}%
  }
  {%
  \end{itemize}
}

\liststepwise
{%
  \begin{stepitemize}
  \item test
    
  \item foo
    
  \item bar
  \end{stepitemize}
}
