The command just calls variable-at-point, which doesn't have any
machinery to go from the displayed data to the actual symbol (which
info-look has).

It's trivial to fix (now after bug#41905 was fixed), but I'm not sure at
what level to do that.  The least invasive way to do it would be to just
redefine `C-h v' in Customize buffers, but the way `describe-variable'
is defined would require a refactor of that function.

`variable-at-point' could grow some way to allow it to be parameterised,
for instance via a buffer-local variable-at-point-function, which would
be kinda clean and is how many similar things are handled...
