Yup, noticed too. Some planes are fine. Like (I think) the 414 is exact matching all the way. And some are worse like the Globe Swift hardly moves at all even at full 90 degree lock, the graphical yoke has only moved about 5 degrees.
But the actual effect on the ailerons is fine so that’s what matters.
My solution is to hide the yokes in planes that you can hide them 
…on most you can. It’s part of my checklist 
You don’t really need to see a yoke if you’re holding one. That doesn’t make sense, haha.
