I wouldn't say "extreme over brightening", but yes, a washed out image is what I was seeing when streaming iPlayer HLG content from the Roku Stick+. The comparison of EOTF curves between the KS TV (bottom) and an MU6400 TV (top) is obvious:

 

 

 


OK so it is probably brighter than it should be - but in no way washed out and nothing that can't be adjusted by gamma or brightness settings.  I compared the UHD version from my VM V6 box (which of course won't sent the HLG) to that of the Roku+.  Both were great and yes the Roku was brighter but also more vibrant.   None of the snow scenes looked any more 'bleached out' on the Roku compared to the VM.

OK maybe not quite as good as a disk but pretty close.  Much better than Netflix or Amazon streams.

 

 

Hmm, not sure I agree with that last opinion . Netflix and Amazon are going to be using the correct curve for their format (ie PQ for HDR10), without any jiggery-pokery.

Tested on each TV using the same methodology, by injecting HLG metadata:

87:01:1a:6d:03:00:3e:21:91:9b:aa:19:f7:08:43:8a:08:39:13:3d:42:40:e8:03:00:00:e8:03:e8:03


Definitely looks like some sort of issue with the way the devices interact. Since the only common factor is the HDFury, that's probably where the issue lies (probably with the infoframe.) The Chromecast Ultra caused issues with HDR content on certain TVs as well, because it was sending the incorrect metadata, and it produced a very washed out image.

 

The KS8000 has the correct HLG curve for its internal apps, so there's no reason why it would use a different curve for external devices. As I said, the M9500 player produces an image that is identical to the internal apps.

Let's agree to disagree on this. I can only judge with my eyes and in my opinion Dynasties looks better than Netflix or Amazon HDR UHD. Albeit many shows in HDR from the streaming giants are excellent.

I've noticed something kinda odd with the 4k firestick, it seems constantly put the TV into 'HDR' mode i.e. changing the default settings to 20 back light etc regardless of the source material. The only time I find it not doing it is when using iPlayer... where it maintains the default settings. Any thoughts?

Good news guys! So I checked in on the Italian forum and saw that the moderator had said the FW is being released by Samsung as from this morning and that people should contact them. So I have and they're sending me out the update on a USB, but could take 5-7 days although hopefully sooner. It was specifically stated that the update allows HDR and HLG via inputs.

Ok sounds good.

If Samsung are releasing this why are you getting it on a USB?  Won't it be released OTA and also via Samsung's web site?  Who do we contact to get this? Not via the Italian forum as I can't join due to strange anti spam question on registration.

So can we have the link so we can ask for the firmware?

Whilst that is great news, I don't know why Samsung don't upload the update to their website at the very least - rather than send out multiple USB's with it. It makes more sense to make it available for all to download and manually install - if they aren't planning to release it OTA.

 

Could you please provide the method/link to the method used to contact Samsung. I am fed up with talking to Samsung support as the person rarely knows anything and feel they are nothing more than telephone operatives, PR in place to talk to customers rather than knowledgeable 'support' staff with the required information to actually 'support' customers. I know its difficult to have all the information to hand about every product and the knowledge to actually help people but its still frustrating to talk to someone who has no knowledge of things - like providing a USB update for KS TV's and don't want to spend hours trying to get to talk to the right people that do.

It does seem odd,  especially that the mods here do not have any information which if they had I am sure they would share. I would also agree when people say they have seen this or have a link to updates then please share.
