FWIW, I use simple definitions like this one for the
eight regexp-level faces, not bothering with multiple
kinds of displays.  (Not saying that's what isearch.el
should do.)

(defface isearchp-regexp-level-8 
  '((((background dark)) (:background "#12EC00003F0E")) ; a very dark blue
    (t (:background "#F6F5FFFFE1E1")))  ; a light yellow
  "Face used to highlight subgroup level 8 of your search context.
This highlighting is done during regexp searching whenever
`isearchp-highlight-regexp-group-levels-flag' is non-nil."
  :group 'isearch-plus :group 'faces)
