I know that mostly if people apply LZW compression it will be applied on uncompressed TIFF image.
That may be because TIFF is one of the few containers (along with GIF) where LZW has near-universal support.

Strictly speaking the compression is applied to raw image data, and results in a TIFF file.

As for Bayer data, Canon (and probably several others) uses a form of lossless JPEG compression on their raw files. At a guess, they presumably consolidate all the green bits, all the red bits, and all the blue bits somehow rather than trying to treat them all together as related data.
