The pinch/zoom feature does not depend on the display controller itself, but on the touch sensor applied on the surface of the display and its controller, if any. Pinch/zoom feature requires a multi-touch capacitive sensor, the type of display module you describe, seem to come with a resistive touch sensor with a XPT2046 controller chip. Resistive sensors are single touch and react on the finger or stylus pressure. You must check your display module description to draw conclusions.

Also note that you'd need to do the zoom in software, an ILI9341 cannot do it in hardware.
