Here's a pretty comprehensive review from the folks over at Blu-Ray.com. As I suspected the surround mix is lossy Dolby 5.0 - I'm guessing that it's the same as the one on the DVD that I have sitting in storage. I'll have to locate it and give it a listen asap.
The Point Blu-ray Release Date February 18, 2020
Thank you for the link to this review. This does not seem like a release I need to pick up any time soon, though I would like to see the special features one day.
