I cannot see that texinfo heading levels get highlighted with different colours
when using outline-minor-mode.

Do you see texinfo heading levels highlighted with different colours
when using outline-mode instead of outline-minor-mode?

If not, then outline-regexp is incorrectly specified in texinfo-mode.

If yes, then could you try to customize outline-minor-mode-highlight.

I do not see any highlighting when using "M-x outline-mode".

This is what I am using

(defvar hdlevels
   '( ("@chapter" . 1)
      ("@section" . 1)
      ("@subsection" . 2)
      ("@subsubsection" . 3)
      ;; ---------------------------------------------------------
      ("@unnumbered" . 1)
      ("@unnumberedsec" . 1)
      ("@unnumberedsubsec" . 2)
      ("@unnumberedsubsubsec" . 3)
      ;; ---------------------------------------------------------
      ("@appendix" . 1)
      ("@appendixsec" . 1)
      ("@appendixsubsec" . 2)
      ("@appendixsubsubsec" . 3)
      ;; ---------------------------------------------------------
      ("@majorheading" . 1)
      ("@chapheading" . 1)
      ("@heading" . 1)
      ("@subheading" . 2)
      ("@subsubheading" . 3) )
   "Sets heading names and levels for texinfo files." )

(defun my-outline ()
   "todo"
   (interactive)

   (setq outline-regexp
      (concat
         (regexp-opt (mapcar 'car hdlevels)) "\\>"))

   (setq outline-heading-alist hdlevels) )

(defun my-outline-hook ()
   "todo"
   (add-hook 'texinfo-mode-hook #'my-outline) )

I tried your definitions, and then outlines are highlighted.

I wonder why outline-regexp defined in texinfo-mode is broken?
What would be a correct regexp for texinfo-mode?

I tried again, and everything gets highlighted in texinfo.
First you need to customize outline-minor-mode-highlight
to the value 'override' (also it's useful to customize
outline-minor-mode-cycle to t), then enable outline-minor-mode
in a texinfo mode. Then you can type S-TAB on a @chapter or @section.
