I can not see any VFAs on the flat surfaces. On the inner arcs I believe it is not VFAs, but model arc approximation defects. They are present on all angles on mine and not affected by the speed.
Worst case for VFA is a shiny darker colored plastic under a harsh directional light.
Usually it looks like this (ignore moire):
On mine X1C it is the worst on 65mm/s 30 degrees. From 150 to 200mm/s it completely disappears.
