@paulkyle For the firmware updates you can heck this link. I expect your TV to be updated already, but in case there are all instruction to check if you have the latest version, and how to install it via USB if you don't.
A reset to factory settings (which at this point is the best thing to do) instead simply clears all the data in the television. The OS (Android) is left untouched. That means that after the reset turning on the TV it is like when you bought it, only with the last firmware version you have installed. So you have to set it up completely from scratch. But I am quite sure HDR will work (otherwise you have a faulty TV, but I doubt it).

After factory data reset under latest nougat firmware netflix show normally UltraHD and HDR (although I am not quite excited about it compared to last year's flagship ks9000) but youtube and amazon still do not show any HDR content.
YouTube doesn't support HDR yet. Or better, I suspect Mediatek messed up the implementation of Google's proprietary Profile VP9.2 for HDR in Android 7.0, because I can manage to have vp9.2 videos downloaded from YouTube playing in HDR (although with ugly, washed results) only from Plex.
Amazon Video must show HDR content in HDR. "Z" and "The Grand Tour" are both in HDR, no matter the resolution if you have low bandwidth. You may try to see if it works with them. If it doesn't I am afraid that there is yet another bug, but this time affecting only XE televisions, because usually HDR always plays (it sure does on my XD80) where supported. Since this is quite a low level issue (down to the Codecs) I am afraid that if it doesn't work you should try a second reset to factory settings.
