9.5" Wheel vs 9" Wheel on MYP. How noticeable will the appearance difference be?

Downsizing to a 255/40/20 tire. The stock is 275/35/21 x10.5 wheel (rear), front is 255/35/21 x9.5 wheel (front). So front is the same basically. I want a square setup with more cushioning, rotatable, etc... So its just a matter of the rear.

But I am stuck deciding between a 9"+35 wheel or 9.5"+35 wheel.
The 9" gives more rim protection, but it is quite a drop from the OEM 10.5" that I'm worried about the stance looking even weirder?

How noticeable of a difference do you think the 9"+35 will be compared to the 9.5"+35 for the rear mostly?
