In Emacs 29.0.50, I checked M-x disassemble RET insert-for-yank-1 RET
and it looks like it uses an 'insert' bytcode operation instead of
funcalling the 'insert' function. I think this is what prevents
overriding of 'insert' from working on byte-compiled code, as explained
in '(elisp) Advice and Byte Code'.
