I discovered recently on my Sony A80J that the combo of ColourSpace + PGenerator can place the display into "DV Calibrate" mode, same as an LG display.
Manual calibration of Dolby Vision in relative gamma space for the Sony greatly improved PQ Curve tracking and RGB balance once PQ EOTF processing was enabled. Dolby Vision picture quality is noticeably improved in comparison to Sony's recommended method of using calibrated SDR grayscale.
I'm guessing all Sonys with display led Dolby Vision are capable of the same.
The addition of similar ColourSpace integration functionality with Sony displays as with LG displays would be absolutely amazing.
