 From a practical standpoint, which is it -177 or -174 dBm?
This is confusing topic.

If for example an FM receiver, does the AM component become irrelevant?


_(snip)__

As Bob stated thermal noise is equally divided between AM and PM
components when a carrier is present.

Both  the AM and PM noise components are -177dBm/Hz their sum is
-174dBm/Hz.
