Yes, .gbr is the official extension.
But G04 is the beginning of a comment.
A Gerber file can start by many others strings (often by %).
Many Gerber files have no comment or do not start by a comment.

In X2 mode, a Gerber file created by Kicad starts by %.TF (%.TF is a file function specification)

Sorry, but expecting G04 as first line of a Gerber file is a mistake.
