The bug
MC-261214 was fixed in 23w16a, bringing the amethyst in the calibrated sculk sensor closer to other similar crosses. However, the fix is flawed slightly, and this amethyst appears very slightly wider than other crosses such as flowers, sugar cane and cobwebs.
This is due to these two texture planes being defined from 0 to 16, rather than 0.8 to 15.2 like most other crosses are.
The same issue affects melon stems and pumpkin stems (MC-236476).
How to reproduce
Download the "plane test" resource pack from this ticket
Download the resource pack attached to MC-236476
Apply both resource packs at the same time
Place a cobweb
Place a calibrated sculk sensor
Compare the two crosses, checking how far they reach to the corners of the block
Expected results
The cross shape in calibrated sculk sensors would stop slightly short of the four corners of the block, like the cobweb does.
Actual results
It goes all the way to the corner, unlike cobwebs (and almost all other cross shaped models).
How to fix
This is a very, very easy fix - just change the 0s and 16s in the two amethyst elements in the calibrated_sculk_sensor.json model file to 0.8 and 15.2 respectively. A resource pack is attached which implements this fix.
I'd strongly recommend doing the same thing for the melon stem and pumpkin stem models as well, since that fix is just as easy. The resource pack attached to MC-212630 fixes that issue.

I just checked, and amethyst cluster models reference cross.json, so I'm not sure what you're going for here.
Can confirm, the regular amethyst cluster model references cross.json, which set the planes from 0.8 to 15.2. On the other hand, the planes of the amethyst crystal in the calibrated sculk sensor model are set from 0 to 16, resulting in slightly wider pixels compared to the amethyst cluster block and most other cross models.
This is by design, to match the amethyst cluster models, not cross.json. It was even mentioned in the report you linked...
