Well, the MU8000 is the superior display, so I'm not quite sure why Dolby Vision would be more of a draw than having a superior image. You're down on brightness, down on contrast, down on black uniformity, and slightly better in color gamut and color volume. And that is based on the SJ8500, which has quantum dots and the SJ8570 does not. So, with the exclusion of QD it would not be surprising if it were inferior in color gamut and color volume, too.
If I were you, I'd be looking at different TV if DV is such a draw for you, something like the P75.
