Advertisements Exactly. Maybe there's some more technologically sophisticated answer (such as using some kind of intermediary device between the TS4K and the TV that correctly remaps the color gamut and dynamic range) but I don't know of one. All I can think to do (until TiVo themselves hopefully corrects the issue with a future update to the TS4K) is to set two different HDR picture settings profiles on my TV, with one of them toned down to try and correct for fake HDR (i.e. make it look more like SDR Rec.709) and the other set for actual HDR. And then switch back and forth between the two profiles on the TV depending on what is being streamed from the TS4K.
