Hard to say, but it looks like "normal" size headshell, so it should be possible to align it to follow the arc. I'm sure you know how to align, but repetition is never bad;
- Loosen the cartridge screws a desired amount. Some people prefer to losen them just a little bit so they can wiggle the cartridge, but this will scratch the headshell a bit. Up to you.
- Move the cartridge further in the headshell, so its almost at the "tip" of the headshell.
- Lower the needle/spin the protractor to hit the first C' point (make sure turntable is level, antiskating is set to 0, and VTF around 1g)
- Make sure not to move protractor anymore -> Cue up, and cue down in few points following the arc and see if the stylus is in front or behind of the arc-line. If the stylus is behind the arc-line near "spindle C point", then you have to move the cartridge forward (towards the camera if we use or photos as reference) and vice versa.
- After the stylus follows the arc, twist the cartridge very slightly (if needed) to align it with the two grids.
I'm sure you knew all this, but just in case.. if this doesn't work, then you can use the 52mm rule (Technics gauge) and just listen the records. As I said, rough diamonds like the one in AT95 are not that alignment dependent. Furthermore, You may require a bit longer break-in time, but the sound will never be THAT great no matter how much you adjust and play around. It is a very cheap cartridge after all, albeit unbeatable in price/quality ratio.
You can try the aftermarket HE or Shibata styli also, but especially the Shibata is a bit on the expensive side. In theory they should reduce sibilance and distortion to minimum, but they require more precise alignment. I have no personal experience with them, so you better check with someone else who has.
