That is a great question. I am not 100% sure of the answer myself, but I
am sure others will chime in.
I used to be responsible for an RF lab in which we did a lot of low-noise
measurements; had shielded racks, chamber, etc. - I can tell you from
anything that can raise or effect the noise floor can affect the
measurement(s). So, in this case, I would think that is true; so I would
postulate that it is possible.
But, there may be some on the list that have made these measurements and
will share their experience and expert knowledge.
