You're correct. Also, a recessed escutcheon installed so that it is flush with the inner ring removes the assembly from being a recessed sprinkler, since the def of a recessed head is no longer met.

If recessed yes, a listed escutcheon for that head. As long as I don't recess the head seems like I wouldn't. As long as the clg is above or right even with the top of the arms the head wouldn't be recessed. Even if there is a nominal gap around the threads, RC or pipe depending on elevation I don't see where even filling/covering this gap is a requirement. This isn't a rated membrane penetration covered in IBC 712.3.2. Even then it's a metal escutcheon which might be a pipe ring not a sprinkler head escutcheon. Chris Cahill, P.E.
