In my experience it really depends on the individual people. When doing my master’s I had two supervisors. One I only spoke on other academic matters and the first actually wanted me to do something else. When the time came to grade my thesis the first supervisor named a grade and the second said “I haven’t read your work but I trust him.” That was it.

In the industry so far I have seen managers claiming all credits for the successes of their underlings (Old style manager) as well as very supportive, enabling, and supportive managers.

So I suppose it depends on which supervisor you end up with.
