That would rely on blood samples having been taken at the post mortem of the two crew. We may never find out if PMs were done, other than routine blood tests for banned substances, The cause of death being done to 'blunt trauma'.
It is widely reported that Doctors and Paramedics have found Covid-19 patients who were lucid and talking and using their mobile phones - whlist having a blood saturation below 70. Usually, at that level, a person is either in heart/brain failure or about to be so within seconds. Covid-19 makes the blood 'sticky' it is report and this typically shows up first in the lungs but also damages other organs.
We come back to the concern about what the FO would do, if he thought the Cpt was not performing to the best of his ability?
