isearch-lazy-highlight-update can't test for non-nil
isearch-mode, because it's also used in non-isearch cases
like in query-replace where isearch-mode is nil.

I thought that your request was for using
isearch-lazy-highlight-window as an argument
of window functions in isearch-lazy-highlight-update.
If you need this, then please create a new request,
and I'm closing this one.
