??? I've just tried, and it definitely does solve the problem here.

Or maybe I don't understand well enough what you mean by "reverts the
effect"?  You've never actually shown a recipe with detailed
explanations which explain what exactly is "reverted".  Because
standard-display-unicode-special-glyphs by itself doesn't change
anything on display in 'emacs -Q", you must do something else to see
its effect.  In my testing, I used "C-x 3", which shows the vertical
border between two windows using a Unicode character when
standard-display-unicode-special-glyphs is in effect.  Before my
changes, whitespace-mode would revert the border back to the ASCII
characters they used originally; after my changes this no longer
happens.

emacs -Q -nw
C-x 3    ;; See the vertical division line with |
S-M-: (standard-display-unicode-special-glyphs) ;; See the vertical division line with #x2502
M-x whitespace-mode ;; See the vertical division line reverted to |
M-x whitespace-mode ;; whitespace mode disabled vertical divisor back to #x2502
M-x whitespace-mode ;; whitespace mode enabled again, vertical divisor stays #x2502




So what is your recipe, starting from "emacs -Q", where you see that
whitespace-mode still reverts the effect of

standard-display-unicode-special-glyphs?

What "special glyphs" are you talking about, and how do you make Emacs
display them?
