If you are using Adobe CC, you will have had, or shortly will have, an update to Photoshop to version 24.0.0 and ACR to v 15.0
While most of your settings will be maintained, there is a little "gotcha" which always seems to happen when there is a major update like this one is.
Open a raw file in Photoshop and it opens in Camera Raw. At the bottom of the frame there is a link which tells you what your output settings are. if you were previously using 16 bit output, you may find it has changed back to the default 8 bit. Click the link and change your setting to 16 bit, then open the image. You should now be back to 16 bit for all subsequent uses in ACR.
