I'm starting to think the same thing. I just got my TS4Ks today finally. After hooking one up and it detecting my Dolby Vision capable display, it shows that it's on, but when I compare it to my AppleTV forced to Dolby Vision it's not even close to the quality I get with that. It doesn't even look like what it's supposed to being converted to DV. It looks like a horrible rendition of SDR. No wonder you guys don't like it being forced on. With the AppleTV it's a completely different story.Honestly, I don't think they are actually using Dolby Vision here and the reason we can't mess with it is that the implementation isn't working properly. On a SDR TV, disabling Dolby Vision actually makes the picture better, colors get less saturated the moment you use the hidden menu item to turn it off. Furthermore, like, how is it even working? Why does the picture even change? How? Are you just saying Dolby Vision is a software thing now? What's up with this?
DOLBY VISION SHOULD NOT EVEN BE AN OPTION ON A NON-DOLBY VISION TV!
There's something really screwy going on with HDR related stuff on the Stream...and to me it's almost like they are forcing Dolby Vision because Dolby Vision isn't actually working properly so it's better to show it "on" without the option to disable to satisfy the advertising. It's not an automatically detected thing, that's for freaking sure.
I bet you this thing was partly rushed out the door to try and save it from the impending launch/announcement of the Google Android TV device. If they waited later, people would just use the Google device as it's rumored to basically eat Tivo's lunch in this arena. They probably figured it was better to get SOME marketshare on a product they were developing vs waiting until Google's offering gives consumers no reason to purchase the Tivo version. Undercut everyone for a month on price, hope people buy it, work out the bugs (if they care enough).
If Tivo can RAPIDLY fix the bugs, and actually bring the Tivo "experience" fully to this device they can compete. If they don't, it's a DOA product.
