Ah, well, I guess that eliminates the possibility of having the TV connect to the US-based firmware servers to revert to the US standard firmware in case anyone wants to do an roll-back. But thank you again for confirming.
So, short of anyone finding a downloadable version of the latest US firmware and/or figuring out a way to take a backup of it off a functioning TV that's running it - and I certainly lack the knowledge/skill to do either one - at this point we have to assume that a roll-back isn't possible. That is unfortunate but still not necessarily a deal-killer for me, at least not yet anyway.
Regarding the non-DV HDR issue with Chris' TV, it seems to me we should focus on coming to a definitive conclusion as to whether a problem actually exists before trying to trouble-shoot it. That is to say, there has to be a way to determine, conclusively, if Chris' TV is still displaying HDR10 even if his TV isn't bringing up a Picture Mode menu specifically labeled "HDR" the way these TVs do when running on the US-standard firmware. I can think of two possible ways to do this:
First, Chris should be able to do a simple A/B comparison of non-DV HDR content from a HDR10 disc played off his Oppo 203 by picking some specific scenes likely to highlight the differences between HDR and SDR (i.e., juxtaposing very bright and colorful parts with dark/shadowy parts), making sure the Oppo settings are set to output HDR10, and carefully watching the result on the TV. Then, turn HDR off on the Oppo and, without making any adjustment to the TV settings, watch the same exact scenes again. If there is a definite visible difference of the sort one would expect to see comparing HDR to SDR between the two, then that should prove that the TV is still displaying HDR correctly even if it no longer has a separate and specific "HDR"-labeled picture mode.
The second way, and certainly this is not mutually exclusive to the first, is to see if anyone can get in contact with LeEco customer technical support in China and simply ask them our questions about EUI6.0 on this TV. Does it still display HDR10 for non-DV HDR content after updating to EUI6.0? What happened to the HDR-specific picture mode? Does EUI6.0 update the TV's Android OS from 6.x "Marshmallow" to at least 7.x "Nougat" or (even better) the latest 8.x "Oreo"? And any other questions I'm forgetting here....

So right now not sure which was to go. Tv arrives on the 8th and will hope it has the latest FW and go from there. He is willing to call LeEco as many times as it takes to get a straight answer...if that is possible
TooMany, this post of yours from a month or so ago indicates that you had a contact in China who was able to communicate with LeEco CS...is that line of communication still open? If so, would you be able and willing to ask this friend of yours to try and get these answers for us?
Finally, I was Googling around on LeEco's Chinese web pages today and did find at least some published info on EUI6.0 for these TVs in China, including this interesting tidbit courtesy of Google Translate: "EUI6.0 is a joint design team developed by China and the United States, with the simplicity and beauty of the global user base, as well as a sense of unity and focus on serving Open Eco and business-as-a-service." From this I infer that there was at least an original intent that some version of EUI6.0 would be made available for US-based TVs; whether that ever happens now with everything that's happened and happening to LeEco in both the US and in China is anyone's guess, but I have to think this is the reason why the latest Chinese firmware works on US-based TVs at all.
For whatever they are worth, these are my best thoughts and ideas on our situation at the moment!
