You are right! Thanks!
Cinavia audio watermark support was added with FW 288 on 8/19/10.
Cinavia audio watermark support was removed with FW 300 on 9/9/10.
It lasted less than a month which probably indicates issues with Cinavia and/or the LG Hardware.
It hasn't been added since but there are no notes for the 362 FW on the site.
To be on the SAFE side, you should check every future update and disable the online FW update just in case there is a Cinavia implementation that can not be removed by reverting to older FW.
Also just in case you should keep all FW files handy, you never know if you'd need one or more of them. For instance, if Cinavia is implemented in future FW you may need to flash to an older FW then to a newer one and then back to an older/newer one to successfully remove Cinavia.
Here are the FW notes from the Dexid site:
