If the input level required by the ICOM transceiver is +10dBm (10mW), DPM could be provided to the LA1K by the ICOM transceiver.
This pre-release information makes claim that "The IC-PW2 has succeeded in realizing the world’s first DPD as a linear amplifier for amateur radio in combination with the IC-7610."
Being the "world's first" sure makes it sounds like said ICOM DPD isn't exactly identical to the PureSignal approach that has been around for years.
This ICOM page has a nice clear pic of their DPD feedback cable providing the needed connection between the IC-7610 and IC-PW2.
Perhaps, owners of PureSignal-equipped LA-1K with IC-7610 (new DPD firmware installed) as the exciter can share their findings with the rest of us.
