Why do you ask?
To turn off HDR while still maintaining WCG/BT2020, you either need an HDFury Integral or the new Vertex, which can do this with the Panasonic, the Philips, and possibly other UHD BD players, or the Oppo 203/205, which has this ability built-in. From what I've read, the Oppo doesn't do this as accurately as the Panasonic/HDFury combination, but how much difference there is, I don't know.
The other option, built into many UHD BD players, is to simply turn off HDR, which will cause it to also get rid of WCG/BGT2020, such that you end up with Rec709, the 'usual' Bluray color space.
With 4k/HDR BD's, there are 3 possible visual advantages (setting aside that often the Atmos soundtrack is only available with the 4k disc): 4k resolution, Wide Color Gamut, and High Dynamic Range. With the HDFury option, you maintain 4k and WCG, losing HDR. With fully turning off HDR in the second option, you maintain 4k resolution, but lose both WCG and HDR.
