Well after some more digging, I believe I found the issue. It's on page 17. So it looks like I'll either have to use a different pc to get 3D, or burn the discs and play them back on my PS3.

We regret it's taken so long to get an answer for this issue. The official statement from Intel is as follows:
The S3D (stereo 3D) technology has been and continues to be supported on Intel graphics via HDMI 1.4. On some OEM PC designs with 6th Gen, 7th Gen and 8th Gen Intel Core processors, a LSPCON (a 3rd party integrated controller on the motherboard) is utilized to convert a DisplayPort signal to enable HDMI 2.0, and S3D is not supported in this scenario. As our OEM partners have moved away from enabling this feature based on low customer demand, S3D via HDMI 2.0 is not currently supported on some 6th Gen, 7th Gen and 8th Gen Intel Core processors. We are actively evaluating support for this feature in future products.
