The input method and prettification both take the "pragmatic" decision of
rendering \phi as GREEK SMALL LETTER PHI instead of GREEK PHI SYMBOL,
presumably because it has better font support or because of consistency with
the rest of the greek alphabet.
Some extra data points:
* The unicode-math package translates GREEK PHI SYMBOL to \phi, and GREEK SMALL
LETTER PHI to \varphi, so the input method is inconsistent with unicode-math.
* The company-math package translates \phi to GREEK PHI SYMBOL and \varphi to
GREEK SMALL LETTER PHI, consistently with your expectations.
