I've tested how the DataGrid behaves with Dark color enabled on Windows and I receive the following result:
Indeed, the search panel and the grouping panel do not receive the dark color, still, the Search entry is properly styled.
I've attached my test app, so you can test it on your side and check whether you get the same result. I'd need to research this in order to find why the Entry is not styled on your side and hopefully find a suitable workaround.
