You are correct, but I was only referring to the V caps!! The 5 bump isn't as pronounced as the 4V
Mk's 5 also have a top end lift when run as cardioids but I believe its different than the mk4v's.
I have both; the 4V does seem to have a bit more of a boost. I also feel like I somewhat prefer the sound, but that's extremely subjective, given that my 4Vs are old, my 5s were bought new, and all Schoeps sound pretty alike...
The 41V, as noted, sounds the same as the 41; it's just a matter of preferring the convenience of vertical caps (I do)
