There are two indent commands
Command: Indent
Alter the indent of the opening system for the current movement.
Location: Object Menu ▶ Movements ▶ Typesetter ▶ Print Layout
Internal Name: Indent
and
Command: Indent
Indent the first system of every movement by the given amount.
Location: Object Menu ▶ Score ▶ Typesetter ▶ Print Layout
Internal Name: ScoreIndent
The Instrument name command
Command: Instrument Name
Print Instrument name before staff at start of score,
Location: Object Menu ▶ Staffs/Voices ▶ Staff Properties
Internal Name: InstrumentName
runs the second (*) of those Indent commands, so to retrieve the value
set you need
(d-DirectiveGet-score-data "ScoreIndent")
to get that value.
The value set by InstrumentName is just a very crude guess based on the
length of the name, a proper job would require querying LilyPond about
how much space is required ...
