Dolby Vision Profile 7 & 8 support (.ts/.mkv files)

The changes for the 2017/2021 models in 7.7.2 are fairly minor in scale compared to the changes for the 2022 model.

As I previously mentioned this will be expanded in the future, but from our point of view it didn’t make sense to hold up the release of 7.7.2 as there were many great additions which were complete and ready to go.
