Advertisements It does switch into Dolby Vision or HDR mode which is the entire problem. On a modern UHD HDR display that is reasonably well calibrated, SDR content will not look good when displayed on a TV in DV or HDR mode. The image is much too bright which destroys details in bright areas and makes the image harsh to view, and the colors are also way off. Doing a back to back comparison of the same content viewed on my Fire Stick 4K which properly switches modes to the Stream which does not, the difference is significant. SDR content looks dramatically better on the Fire Stick.
