Panasonic G9 V-log l raw footage gets auto adjusted

We have the Panasonic G9 with the Vlogl firmware upgrade.  Normally use vLog with video, but in high contrast situations, we use vlog on stills to reduce the contrast and keep the shadow detail.

On the back of the camera, footage shows no blown highlights and can see shadow detail.  However, when open in ACR, the image highlights are blown and the shadows are under-exposed.  The histogram on back of camera shows plenty of latitude for both.

When do we need to do in ACR, to open file correctly?  We would like to make our own adjustments.
