Directly under picture adjustments you will see the source. To the right of the source, directly across you will see the HDR flag. If you do not see this, you're set is not receiving an HDR signal. The "Cinema Pro" selection you are seeing will be on the next row down.
On Netflix, I do not see the HDR in Picture Adjustments on either the native Netflix app or on my Roku+. When I press display, it reports 3840 x 2160p 4K. However, I do see HDR in Picture Adjustments when using Amazon Prime both native and Roku. I have the HD subscription to Netflix. Any ideas? Once again, thanks for your help with the query.
