BROOKLYN 19,
The answer to your question actualy is YES it does say in the Gemara wich parts of the body are considerd ervah
The gemara is torah shebal peh that was passed down to us from person to person directly from har sinai.
to compare the words of those gemaras wich are explaining what is meant by a possuk as was passed down directly person to person from har sinai to a nowadays godol’s opinion of what is to “flashy” or “loud” when even the godol is not claiming to have heard this directly from somone who heard it at har sinai (as the gemara did) is just wrong and missing the entire point.
