I, too, have a high palate and experience the same flat pitch across the
board. I've often felt that the high space in my mouth has something to =
do
with this phenomenon. I'd be interested in some info on the subject, too.=

Acoustically, this is possible. The pitch of a note is governed by
(a) the vibration source, ie reed/mouthpiece.embouchure
(b) the interaction between two resonant spaces, the clarinet itself
with the fingering used, and the cavities behind your teeth.

So in principle a high palette, forming a larger volume and hence =

lower pitch resonator (Helmholz resonator), could pull down the
pitch of a clarinet compared to another player using the same
mouth configuration.

But it should be possible to adjust for this. We have huge control
over the shape of our mouths inside, and we tend to make an 'eee'
shape for high notes anyway. Maybe you should try this for lower
notes (without impeding the airstream). Let us know how you =

get on!
