Explain me wheel dish as it relates to change to 11sp

I’m hoping someone who understands wheel building can explain this to me:

I currently have a 10sp set up (SRAM red FWIW) if I was to upgrade to 11sp I have been under the impression that I would need my rear wheel re-dished. I currently have a chris king R45 hub which the free hub body is 11sp compatable. I currently use the 1.5mm (I think) spacer to make so it can work with the 10sp set up.

I would love if someone could explain why this logic is wrong, or tell me I’m right: The imaginary ‘center’ of the rim should be at the middle of the axle in a properly dished wheel. This should not be affected by whatever cassette happens to be attached to the free hub body. If you were to re-dish the wheel in any way (assuming the same hub) wouldn’t you have a wheel/rim that will no longer be centered in the dropouts and by extension not centered under the brake or behind the seat tube.

Or, is the whole need for re-dishing not true and all I would need to do is remove that spacer?

Thanks in advance.

If you have an 11 speed freehub then no need for redishing. It’s only if you go from a 10 speed freehub to an 11 speed.

That’s it!
