Campagnolo Potenza real derailleur loves a bent derailleur hanger?!

I have a Campagnolo Potenza 11 speed groupset on my Bianchi Oltre XR3 2018. I bent my derailleur hanger and bought a new one. Of course, I checked its alignment with a proper alignment tool (and also a second one that I borrowed), so the derailleur would move parallel to the cassette.
However, the shifting was always uneven across the different gears. I then bought a new Potenza derailleur (maybe the old derailleur itself got bent?) and replaced all cables and housing making sure there were no kinks in the cable. Still the same issues. When standing behind the bike and looking at the derailleur cage, it didn't seem to be in one line with, for example, the smallest gear / largest cog of the cassette ... which seemed strange since the hanger was aligned perfectly on the y-axis and x-axis!
I then deliberately bent the derailleur hanger toward the wheel to get a proper cassette-derailleur cage alignment. Shifting has improved dramatically. But why would I need to bend my derailleur hanger out of alignment?
Has anybody experienced a similar issue with Campagnolo or am I missing something? I know, I shouldn't complain since the shifting seems more or less fine now. But why on earth does a Campagnolo derailleur (brand new) require a "misaligned" derailleur. I always thought that a well aligned derailleur hanger is an absolute basic prerequisite for precise shifting.
Thanks in advance for sharing your experience or advice!

Have you checked the frame alignment?The above may be fact, or fiction, I may be serious, I may be jesting.
I am not sure. You have no chance.Veronese68 wrote:PB is the most sensible person on here.1 -
Doesn't the alignment of the hanger take the frame out of the equation?0

Not if the frame is damaged.The above may be fact, or fiction, I may be serious, I may be jesting.

Frame has no visible/audible damage. Maybe I'll try a chorus derailleur to see if this is specific to the Potenza line.0

Frame material?
I ask as steel, aluminium and titanium can be bent. Carbon less so.The above may be fact, or fiction, I may be serious, I may be jesting.

1, look at your wheel in the bike, is there an even space between the frame and the wheel? if not, try another wheel if theyre both uneven then either the dishing is out on both wheels or the frame isnt in alignment.
2, see if your local bike shop has a frame alignment gauge and check.
