Raw compression R5

Not yet having the camera to do some tests I have a question about the compression of the RAW file during the bursts.
From the manual of R5 it says this
RAW, C-RAW 14 bit (14-bit with Mechanical shutter and Electronic 1st Curtain, 13-bit A/D conversion with H+ mode, 12-bit A/D conversion with Electronic shutter, Canon original RAW 3rd edition)
from the way it is written it would seem that only if you shoot in uncompressed RAW format there is a decrease of the bit depth
Canon original RAW 3rd edition
but not in CRAW am i wrong?


Ps: sorry for my bad english but i'm Italian :D
