Will the pressure carburettor make corrections for variations in temperature of intake air like the pilot can do with manual leaning? For example, will the

mass fuel flow ratio be the same with using pressure carburettor if flying with 20" MAP at 30°C or -20°C?
I seriously doubt it. The only way to get rid of manual leaning (and still maintaining correct air-to-fuel or fuel-to-air ratio - and not destroying the engine in the process) is via electronic fuel injection, where ECU (Engine Control Unit) calculates the amount of fuel to be injected into cylinders by using many sensors (temperature and pressure of intake air, etc.).
