No such thing as 8 bit color 4K UHD broadcast . /10 bit 4K HD lite will probably result in many re transmission cases eg, CATV/SAT (whenever they get around to it anyway) see rec .709

and rec .2020
and current ATSC
and HD Lite
All should answer many questions many may have .
A lot of us here have read those or things similar ,your turn in the barrel now
Keep in mind OP linked article is only talking about 8 bit HEVC vs 10bit HEVC re transmission + STB (in a basic manner ) not panel display color bitrate depth or display modes or terrestrial OTA broadcast
but more likley HEVC 4K UHD lite
Not to mention as far as USA goes much of that article *may be speculative *
Stay tuned to AVS !
They can run 8 bit panel in 10 bit overdrive (8 bit [+high FRC ] )
, panel should display 10 bit color just fine , Advantage for native 10 bit panel would ofc be less (sometimes seemingly aimless) dithering under low birate /no signal
and smoother color gradient+ eg,less color banding ..
Sony is using 6 bit [+high FRC ] (8 bit overdrive display mode ) panels in all the 2014 W600b and maybe *some others and reportedly in 2014 70W850B aslo
I have a 2013 40" R4 Sony Bravia like that with Sansung S-PVA4
6 bit [+high FRC panel ] best in class picture better than 2014
same size and some bigger Vizeo FALD .
10 bit 4K panels *may be resrved *for premuim 4K sets depending on mfr.
In any event x bit +[high FRC ]panels can otherwise look very good as good as higher bit panels often .
especially with low blacks/high contrast in all but a few cases eg, *some 10 maybe 12 bit bit Sony 9 / 9.5 x
** note there are are currently 8 bit + high[FRC] UHD 4K panels entering production alongside the usual 10 bit UHD panels .**
Here are the black/contrast on (2013 Sony R4 and 2014 W600B with
6 bit + [high FRC] Samsung S-PVA4 Panels .
Also 2014 W800/850B + 950B presumably 8 or (some) 10 bit panels .
5 Sony black level + contrast Comparison
2013 Sony R450A Black: 0.022 cd/m2 Contrast: 4750 : 1 Samsung SPVA
2014 Sony W600B Black: 0.026 cd/m2 Contrast: 3500 : 1 Samsing SPVA
2014 Sony W800B Black: 0.020 cd/m2 Contrast: 5260 : 1 AUO AMVA5
2014 Sony W850B Black: 0.026 cd/m2 Contrast: 4273 : probably AUO AMVA *panel mfr/type/spec may vary by size
2014 Sony W950B Black: 0.111 cd/m2 Contrast: 942 : 1 >>>> LGD IPS
Notes : AUO AMVA and Samsung SPVA are both VA panels LGD are S-IPS
AUO AMVA 3D (usually active *can be passive also )
All 3D Samsung are active .
All 3D LGD are passive .
