Yes, the Wurlitzer Caliola uses the APP scale, and could play the
standard APP roll.  Wurlitzer did indeed produce rolls that were
specifically intended for use on these instruments.  The holes were
elongated, giving the instrument a much more "organ" like sound.
Regular APP rolls on a Caliola sound "choppy".

The late John Maxwell had the largest collection of the special
Caliola rolls known at the time of his passing.  I don't recall who
wound up with them.
