Hi... Happy New Year!
I am not sure if the well depth has anything to do with the instrument pitch. The instrument tone holes are positioned based on the location of the reed vibration point regardless of well depth, which I think is few mm off the tip of the staple. If the position of the reed vibration point is changed, i.e. reed is pulled out wheather or not the void in the well is filled, the tone hole positions of the instrument would become out of alinment. Generally, that should cause the notes with most of the holes closed (such as low Bb, middle C#, D..) to be slightly out of tune compared to those with mostly open tone holes (mid C, B..).
The more tone holes are open, the note we play has a more room for lip adjustment. So we do not notice as much.
