I have found out a web page that gets A grade at ssllabs, but it redirects all of the traffic from https to http and just marks PLAINTEXT in orange.
And don't forget it most probably gets into SSL Pulse as A site, isn't it? Overall results of SSL Pulse are so higher then it should be.
Test already checks this, but does not take into consideration the grading.
I have made this test because I have found very interesting debate in https://blog.qualys.com/ssllabs/2016/11/16/announcing-ssl-labs-grading-changes-for-2017 article between Francis and Ivan (click on image to enlarge):
