VCP Version 2.0
Controller manufacturer and model: unreported (VCP feature code C8 unsupported)
Firmware version: unreported (VCP feature code C9 unsupported)
Manufactur year: 2012
Color temperature increment: x0B 100 degress kelvin Color temperature request 35 -> 3000 + 35*100 = 6500
VCP Version 2.0
Controller manufacturer and model: unreported (VCP feature code C8 unsupported)
Firmware version: unreported (VCP feature code C9 unsupported)
The capabilities string has 2 additional sets of features, designated vcp_p02 and vcp_p10, in addition to the set specified in the vcp() field. It also reports the commands xC2, xC4, xC6 and xC8, which are not part of the DDC/CI specification. Likely these commands are feature request/response pairs for vcp_p02 and vcp_p10.
Does not use the usual VCP codes (e.g. x16/Red Gain) for color control. Instead uses the 6 axis color control features x8c..xa0.
Has an internal hardware LUT, but it is not accessed using the MCCS defined features for LUT mannipulation.
Uses a proprietary USB for communication, which does not support adhere to the USB Monitor Control Class Specification.

Implements both I2C and USB interfaces.
Makes heavy use of manufacturer specific VCP feature codes. Also, ddcutil capabilities --verbose reports numerous manufacturer specific DDC commands The USB interface also makes heavy use of manufacturer specific usage codes.
Monitor must be set to ??? to allow changes.
VCP code x0c (Color Temperature Request) returns 0, which is nonsensical.
Does not use the usual VCP codes (e.g. x16/Red Gain) for color control. Instead uses the 6 axis color control features x8c..xa0.
