With DV off, are you getting the correct colours now for the SDR/HDR10 test patterns? If so, it's something that should be easy for Ugoos to fix as bobby mentioned (match content colourspace with DV on).
Good news, both HDR10 and SDR modes are accurate in 12bits on the UGOOS. So this the best android device for HDR10/DV/SDR + lossless audio.
HDR10:

Strange that SDR in 8bit 444 is not accurate because my HTPC and x700 are both accurate in 8bit or 12bit.
Great, thanks for the test. So basically the problem as I understand it is:
With TV-led Dolby Vision turned on, the output is currently forced to:
- SDR: 8-bit YCbCr444
- HDR10: 8-bit YCbCr444
- DV: 8-bit RGB
With TV-led Dolby Vision turned on, the output needs to be changed to:
- SDR: 12-bit YCbCr422
- HDR10: 12-bit YCbCr422
- DV: 8-bit RGB
We have confirmed (with Dolby Vision off) that 8-bit YCbCr444 gives the wrong colours for SDR and HDR10, and 12-bit YCbCr422 gives the correct colours for SDR and HDR10. TV-led DV output is 8-bit RGB (as it should be) and gives the correct colours.
I'm not even sure why when TV-led Dolby Vision is turned on, SDR and HDR10 are forced to 8-bit YCbCr444, since when DV is activated it switches to 8-bit RGB anyway. Force DV always on seems to be working as intended and outputs everything in 8-bit RGB.
