We've tested this exact camera against a real RAF sample file and independently verified the shutter count against exiftool — this one is confirmed working.

Shutter count for the Fujifilm GFX 100 is read from MakerNote tag 0x1438 (ImageCount, high bit masked) in the camera's RAF file metadata — entirely in your browser, the file is never uploaded anywhere.
