Low suction pressure high head pressure.
If the compressor has a greater ability to lower this pressure, it will tend to make the evap run at a lower pressure overall. If you attempt to bring up the suction pressure by adding more refrigerant, you'll be stymied by high head pressure and a suction pressure that does not come up much (with a TXV it likely won't rise at all).
