It should only show the line of index 3, so the output would be:
Code:
3 200

---------- Post updated at 17:51 ---------- Previous update was at 17:49 ----------

If you turn the 2nd grep with an modified awk it could look like this:
Code:
gphoto2 --get-config /main/imgsettings/iso | \
    grep -v [LTC][auy]] | \
    grep ^3" " | \
    awk '{print $3}'

In this case we first filter out the Label, Type and current, and then limit the output to index 3, and using awk to just print the value of 200.

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
