Yup done that (DDU in safe mode) and it is looking good using what you just posted (just running a UHD BD now to check the frame repeats). The only stuff that I guess will not work is titles like Billy Lynn (UHD @ 60p with HRD). I've read the JVC Calibration thread and got the Spyder5 Ultra ready to go now that the basic config seems to be working well - Thanks for the clear post all in one place
Edit - and resetup and test BD - 3D
