Remove Three UK Branding?

Hi All and apologies if this has already been answered elsewhere.

I have just recieved my LG G4 (H815) on the Three UK Network and was wondering if anyone was able to point me in the right direction to remove the "Three Branding" found on bootanimation and shutdownanimation?

I have rooted using "Low Effort Root" and replaced all locations with the LG bootanimation and shutdownanimation and ensured all permissions was set to 0644 (rw-r--r--) but I still get the "Three" logo appearing right at the end of the LG bootanimation.

Any ideas folks?

Thanks in advance.
