Default SFR and Vodafone's kitkat kdz are the same?

I've downloaded SFR and Vodafone(Germany)'s kikat kdz from the below website:
http://lg-phone-firmware.com/index.php?id_mod=36

But when I flash the SFR kdz, it boots with vodafone's bootanimation, and I saw these two kdz are totally the same file size.
(Both are 1,847,271,518 bytes)

Is it normal? And is there anyone who flashed SFR kdz but shows with Vodafones bootanimation?

I was wondering if LG put the wrong one, also I've tried to redownload 3-4 times.
