I would also mention "MIPI CCS" instead of "CSI-2".

"bits per sample" is very ill-defined for metadata, as there's no
sample. I would write "for both the RAW8 packing and the 2 bytes RAW16
packing" or something similar.
Similar comments for below.

It sounds really weird to write that this format writes 10 bits for each
8 bits of data, when essentially it adds a packing byte every four
bytes.

Again, it's CCS, not CSI-2.
