LG Service Menu / Mode Access

If a "universal" remote (ie: 1056B01 / JP1) can be programmed with a 3 to 5 digit code to EMULATE the original user remote for most TVs and other devices, can it be programmed to emulate a "Master Service Remote"? I have LG 32LH20R and NONE of the online postings using the original consumer remote (menu + menu, etc.) have accessed to service menu mode.
