I've added a guard and made minor tweaks:

if [[ $'\e\x5b3D' == "$(echoti cub 3)" ]] &&
   [[ $'\e\x5b33m' == "$(echoti setaf 3)" ]]; then
  zstyle -e ':completion:*' list-colors $'reply=( "=(#b)(${(b)PREFIX})(?)([^ ]#)*=0=0=${PREFIX:+${#PREFIX}D${(l:$#PREFIX:: :):-…}\e\x5b}34=33" )'
fi
zstyle ':completion:*:*(directories|files)*' list-colors ''
