I do not think so. The insulating material is flexible and fits
tightly. Also, the TC is against the flat surface of the nut,
I don't think so. The wire is against the nut, but it is not clear
the thermocouple tip is.
and probably it is snugly covered on all sides.
HOWEVER, if you think this is a concern, we can test for it. We can
make a tent as large as you like, and see if it makes a measurable
difference. The string tent I made is probably bigger than anything
in your description of Rossi's setup. Also my string tent had a
cold water pipe running through it with lots of 16°C water flowing
through, 1 cm away from the TC. That seems more extreme than what
you are proposing.
Heckert can also test for this with some insulation.
