Different volume for phono vs line level

[Mont Blanc]

I have two inputs to my D140 which require very different gain settings to achieve similar listening volume. Streaming via Roon over ethernet, volume setting is around -25db for normal listening. Analogue phono input needs to be turned up to about 0db to achieve similar volume. My cartridge output is .4mV with the phono gain setting at .5mV in the configurator. 

Anyone else experiencing something similar? If normal, I'll leave it alone, but it seems odd.
