Aside from when running in class A is the Mark IV always simulclass? I recently read that it is only simul when running in triode mode but that didn't sound right to me. Definitely got me wondering though.

Class A or Simulclass. The Triode / Pentode mode has no effect on this in any way.
The fact that Stephen appears from nowhere, is sentenced to death in an emotional public trial without anyone interfering at all and is then altogether forgotten as if nothing happened, is already suspicious.

The Pentode/Triode switch affects the outer pair of tubes in Simulclass mode. Not sure how it works when the amp is switched to Class-A mode (outer tubes only).

Pentode/Triode works in Simulclass and Class A.
