After powering up the system, we can finally see what this drive supports or not, by using well known optical storage software, that more or less reporting the exactly same specifications:

The drive came with 1.01 firmware revision and its identified as BDR-X13U and has build-in 4MB of buffer included. After we finished our tests, Pioneer released a newer firmware update to 1.02, which was used to perform additional tests for reading again various discs since the change log mentioned "improved reading performance". The firmware update process is rather simple, you download from Pioneer Japan a firmware update file and the drive will automatically be updated, note that you cannot revert back to previous firmware version if you wish to update.

The drive with OptiDriveControl and other benchmarking software can report back "C1/C2, PIE/PIF" measurements, while doesn't support CD Bler, FE/TE and Blu-Ray disc measurements. The drive also "fails" when scanning Dual Layer discs with DVD Format (no idea if its a software bug or drive limitation).

For detailed information on Ultra HD Blu-ray playback, refer to this page The Intel Software Guard Extensions (Intel SGX) feature is a requirement for the CPU and motherboard firmware to play DRM (digital rights management) protected content on Ultra HD Blu-ray movie discs on a Windows® platform. Note Intel SGX has been removed from Intel 11th generation and newer CPUs, and support for SGX may be removed on new versions of Intel drivers or utility programs such as Intel SGX and Intel Management Engine drivers and firmware in the future. Such changes could cause these platforms to lose support for Ultra HD Blu-ray movie disc playback.
