use of RS5 17663.1 or 17663.107 + lastest CU

I notice that the resulting .iso is bigger if I use 17663.107 + Windows10.0-kb4467708-x64 -CU.134.msu
both lead to .134 but with my .wccf it goes from 6 054 036 Kb to 6 199 698 Kb

sorry I forget to put my question
does the result .iso install the same updates? 
If not, can I use some Winreducer actions to have the same size (almost the same …)

THanks for the help

Hey

I'm not sure to understand correctly because each time you integrate updates, net framework 3.5 or drivers in your ISO, the ISO size will grow according the amount of new files you integrate

But the only difference is the .iso the .wccf is the same for both reduction.
As the Initial .iso's are different size I can imagine that the result will be according to the initial size.
But my question is the reduced .iso's will install Windows in the same state?
