Uncompressing a LZ4 blob with Perl

I have a table in a SQLite db that stores blobs compressed with LZ4 algorithm. I am trying to use decompress/uncompress functions from Compress::LZ4, but not getting any success with it.

The sample SQLite db can be downloaded from here.

Here is how I am connecting to the SQLite db and getting the blob:

use DBI; 
use Data::Dump; 
use MIME::Base64; 
use Compress::LZ4;    

my $dbh = DBI->connect("dbi:SQLite:dbname=$ARGV[0]","","");   
$sth = $dbh->prepare("select blob_data from blob_parts where data_fk = 6");
$sth->execute();   
$result = $sth->fetch;   
$blob = $result->[0];

dd $blob;
dd (decompress($blob));

$sth->finish();  
$dbh->disconnect;

For the particular blob that I am selecting in this sample code (data_fk=6), dd outputs the following:

"LZ4\1>\1\0\0\xF7\xD6df\xF1mBXML\1\xA1\aVersion\xA1\4Type\xA1\2Id\xA1\3Ref\xA1\4Size\xA1\3use\xA1\4expr\xA1\5value\xA1\4data\xA1/Serialization\xA1\aPoints3\xA1\tuser_ E\0\xF0\16\bvertices\xA1\6double\xA1\bhas_attr\xA1\16\n\0\xC7object_ids\xA1\n\f\0\xF1M\4item\xA1\tis_active\xA0~B\20\n\22\6\4\x8C\1\0\0\0\6\2\xAA\24\6\0\xA4\x82\x88\2\x80\x82\x82\xA6B\26\6\b\x80\1B\30 \6\b\x88\2\3B\32\1\x93\6\0\0\0`\xACu\xCF\xBF\0\0\0\0\xCC\xF8\xC2?\0\0\0\0\0\x004\@\0\0\0 \xAA\xEF\xA9\20\x001h\xC5\xB1\b\0\xD0\0\0\$\@\1B\34\x85B\36\x87B C\0\xF0\aB\"\6\0\x88\3B\$\x85\1B\"\6\0\x88\3B\ $\x85\1\1\1"

But the decompress/uncompress functions just return undef. The uncompressed data should be something like (The following output is generated by a XML converter):

<?xml version="1.0" encoding="utf-8"?>
<MultiStreamDocument>
<!-- Stream 1 -->
<?xml version="1.0" encoding="utf-8"?>
<data xmlns="" Id="1" Type="Points3" Version="1 2 0 1 1">
    <user_data Size="0"></user_data>
    <vertices Size="2">
        <double>-0.24577860534191132</double>
        <double>0.14821767807006836</double>
        <double>20</double>
        <double>0.050656620413064957</double>
        <double>0.069418430328369141</double>
        <double>10</double>
    </vertices>
    <has_attr>false</has_attr>
    <has_object_ids>true</has_object_ids>
    <object_ids Size="2">
        <item Version="3">
            <is_active>false</is_active>
        </item>
        <item Version="3">
            <is_active>false</is_active>
        </item>
    </object_ids>
</data><!-- Stream size: 126 bytes -->
</MultiStreamDocument>

What is the correct way to get uncompressed blob data from this SQLite database?
