Ok, so I found something odd: Remember that post last page I made a step by step comparisson of windows images?
Well, turns out I forgot to delete the Secure boot update from my image and 'pure' updated windows wasn't installing.
But that's the normal part.
The weird part is that when I redid the update run of NT, I forgot to mark Dism cleanup, the I did another pass just to do that.
The difference is brutal:
Previous Attempt (Integrate and cleanup in a single run):
With separate runs to integrate and cleanup:

(Please don't mind the broken theme, that was me going a bit too wild with the delete key XD)
Either way, I'm going to redo the experiment again tomorrow, but is this 'normal' DISM behavior or some other trick I simply didn't knew about?
Edit: Did it again, result is the same. From now on, do integration in one run, then dism cleanup on another. Images will be smaller as a result.
Also, word of advice: If you're into a recent laptop (5th+ gen of intel) KEEP Group Policy Editor or the thing will not be able to shutdown. Thermal Framework will also give lots of errors making the device run much hotter than it should.
I also found to leave some services enabled at the installation, like Windows search, and manually disable them later. Modern control panel gives me grief ortherwise.
