I think the consensus on AVS forums is the KS does not recognise the HLG signal as HDR and is clipping it to SDR.
That isn't the consensus. Many people are aware of the fact that HLG is supported internally. Fewer people know that it is supported externally via HDMI, but that's been proven to be true as well.
The issue with DirecTV is that DirecTV's equipment is having an issue communicating with the KS series TVs. Since the TV does support HLG over HDMI, this issue could be fixed with an HDfury, which allows for EDID management.
So what do we make of this
A clarification about the Samsung TVs 2016 (K series)
Currently through HDMI do not yet support the HDR HLG (Only via USB and Tuner support HDR HLG)
Soon will come a new version sw that will also enable HDMI to HDR HLG
While the models 2015 (J series) of Samsung will never be made compatible with the HDR HLG
Would'nt be great if Samsung would end all this speculation and tell us the facts. They must know because the built it. It is very strange why they will not and it would end all this speculation and at times ugliness. @AntS can you try to see if Samsung will answer these points that keep coming up which should end all this and we can get back to discussing what this thread is all about.

What I make of that is that whoever wrote that is wrong and that they have no clue what they're talking about.

Have you got feedback from Samsung?
I dumped EDID of KS8000F with FW 1207. The related block is as below (missing Hybrid Log-Gamma bit).
Extended tag: HDR static metadata data block
Electro optical transfer functions:
Traditional gamma - SDR luminance range
SMPTE ST2084
Supported static metadata descriptors:
Static metadata type 1
For comparison another LG TV working with DIRECTV HLG has Hybrid Log-Gamma bit enabled.
Extended tag: Colorimetry data block
BT2020YCC
BT2020RGB
Extended tag: HDR static metadata data block
Electro optical transfer functions:
Traditional gamma - SDR luminance range
SMPTE ST2084
Hybrid Log-Gamma
Supported static metadata descriptors:
Static metadata type 1
Either Samsung or DIRECTV may misunderstand how to interpret HLG support here.

The first one flags SDR and ST.2084 EOTF support (i.e. HDR10), the second one flags SDR, ST.2084 support and HLG support.
ST.2084 is used by HDR10, Hybrid Log Gamma is HLG.
I'd only expect the second one to work automatically with HLG HDMI sources (as it is the only one flagging HLG support), but both to work with HDR10.
It may be the first set doesn't have HLG support, but if the first one has HLG support for internal streaming sources it may be possible to force HLG modeI manually (I'm guessing the DirecTV box doesn't check for HLG support as it is using the SDR compatibility feature of HGL to send the same content for both SDR and HDR displays?)
My Sony XE9005 (UK version) has both HDR10 and HLG support - but when I play HLG content from a Roku Streaming Stick+ I have to manually switch to HLG mode to display the HLG content in HDR (either the Roku doesn't flag it or the TV doesn't switch)
I may be wrong but I think HLG support was initially only part of the HDMI 2.1 standard, and initially we were going to have to wait for HDMI 2.1 displays for HLG support. However it was agreed that it could be added to the HDMI 2.0b spec as well (or HDMI 2.0b displays could support HLG without adding any other HDMI 2.1 features) - to allow HDMI 2.0b sets to be upgraded to HLG with a firmware update, or HLG support to be standard on HDMI 2.0b sets.
Interesting
