Now that you mention it, yes, and this smell should be detectable at the uncaulked back end of the WC.
On WC removal the relative heights can be checked but I'm not sure how much a wax ring is supposed to be compressed.
". . . so that it compresses just enough to form a good seal without squeezing out into the drainage path and causing an obstruction.
The wax ring should be compressed around 1/2 to 3/4 it's [sic] initial height once installed. "
You da' man, Mistuh W!
