    Yes, from user reports I have seen forced HDR is still an issue with that box. Honestly the ability to automatically match color space (auto switching to HDR/DV based on content) is a requirement you need to look for in any streaming box you are going to buy, IMHO. There are many available, Android based and others, that do that. All of the streaming devices I use support it.

    Maybe, maybe not. It is also important to know which HDR modes are supported.

    Make sure any TV you acquire can handle HDR10 and HLG -- absolutely no exceptions. Adding DolbyVision is the only practical step up. There are about 350 theatrical releases available in DolbyVision at this time.

    Content support HDR10+ is limited and isn't making much progress (if not losing ground). It is what Samsung (and Panasonic where their TVs are marketed) offers instead of DolbyVision and while is has similar functionality, it is not compatible.

    HLG is what the rest of the planet uses for HDR/WCG and is an integral part of NextGen TV (ATSC 3.0) so that's why it isn't optional.

    Thanks folks for the info... the ones I’ve been looking at all seem to have the option to turn HDR off if needed. So at least I’ll know that is an option if I end up having problems with the Osprey box picture.

    Honestly turning off HDR is not a really good option. Plain 4k without HDR/DV is a real yawn IMO and you would still have to turn HDR on for HDR content to get the colors correct. And you don’t want to have to manually switch it on/off. And if it is forced on for all content the colors in non HDR content will be noticeably wrong. In today’s world a streaming device that can’t do auto color space switching is just not competitive. Although again you do need to take into account the market AT&T is targeting with this box...

    I haven’t noticed that being a big issue on my 75” Sony X900E. Colors are fine regardless of box I’m using on it. The only difference is slightly less overall brightness on the ATT box compared to ATV4K, FireTV and Roku Ultra.

    Yeah, I’ll have to see how it works out with the particular TV I end up getting. I only use the Osprey box for ATT TV watching, I don’t use it for any of the streaming apps. I have a Shield, AppleTV 4K, and FireTV that I use for everything else.

    The problem isn’t really whether the box leaves 4K HDR on for all sources. It’s whether it or the display maps it correctly when it does!

    This is mostly addressed by obtaining a TV that fully supports the HDR/WCG schemes that your source material is in.

    My guess would be your tv is mapping the colors correctly. If it didn’t most people would definitely notice it, although admittedly not all. Heck many folks leave their tv’s set on factory default picture settings and are perfectly happy...

    In general this is true but even on my LG OLED65B7A, which does color space mapping rather well, I still don’t keep any of my streamers in forced HDR mode. I set the them to auto match...

    Yeah, that’s probably what’s happening. The Sony I have is upper midrange model and Sony does a very good job with TVs in all their models.

    That said, for all the complaints I see in some forums about the forced HDR that all the AndoidTV version 8 do, in other forums that are not as full of ‘experts’, you don’t see it mentioned much at all.

    Alot depends on the TV also.. The cheaper HDR TV's lack the color and brightness to even do real HDR so it isnt an issue

    Most of the most expensive TVs (OLEDs) lack what it takes to sustain the highest brightness levels that the dynamic HDR formats support.

    Not just the TV, but also the source that’s doing the forced conversion. I’m guessing that’s why you said “mostly” though.

    My LG 65C8 looks incredible with all sources sent as DV with my AppleTV 4K. DV conversion is much better at this than just being converted to HDR10, which is where I think most complaints of doing this are coming from. Forced HDR10 definitely doesn’t look as good as forced DV, but can still look really good if you do some tweaking.

    But I think their tone mapping, especially with DV/LLDV, more than makes up for that. It doesn’t seem to be such a big deal with today’s sources anyway considering the “is it real HDR” reports recently from Vincent Teo from HDTV Test fame. Most discs and almost all streaming doesn’t come close to having higher peaks than the 700+ nits OLED offers anyway.

    I’ll take the much higher native contrast and gorgeous blacks over the slightly limited peaks.

    Maybe, maybe not. I'm not sure it has been demonstrated that it is technically superior to HLG or HDR10+. DV is currently somewhat better supported but I expect that HLG is more likely to catch fire as it will offer content owners and distributors a much larger audience (through universal deployment in all future televisions) in a marketplace that seems to be confined to home theaters for a while.

    HDR10+, as a distraction from the others, can't die soon enough.

    HLG is a compromise to get HDR through older gen broadcast equipment without the need for metadata, so it’s compatible with legacy SDR gear. Without this metadata to inform the display/decoder of the frame or scene’s exact info for how it’s supposed to be shown, it will never match up to DV or HDR10+.

    HLG is dynamic much like DV and HDR10+.

    HLG supports 10-bit HDR (versus Dolby's 12-bit) and doesn't command a royalty paid to Dolby Labs every step of the way. Of greatest importance to the OLED snobs is that HLG supports the full brightness range (0-1000nits) that consumer OLED displays can reproduce.
