I can't recreate this; I've checked a bunch of our production sites and they all validate correctly with a Content-Type header of application/xml. Do you have an example you can share?

For anybody else who has this issue and find this thread, the cause was actually our server enforcing trailing slashes on URLs. Sitemap was not excluded from this rule, so the sitemap.xml request was being redirected to sitemap.xml/ thus giving an incorrect Content-type header when validating the file.
