Samsung is supporting HDR on all 2015 tv's yes that means JU series Too. Sony made a similar announcement yesterday.
“Samsung will issue a firmware update that will enable its 2015 SUHD and UHD TVs to display a broader library of High Dynamic Range (HDR) content now from external devices. HDR delivers a much higher level of contrast between light and dark to produce an image that is more realistic and closer to what the content creator imagined. The firmware update is available now at no additional cost to owners of 2015 Samsung SUHD and UHD TV’s.” wrote Samsung
This also means that Samsung’s “regular” Ultra HD TVs will be capable of reading HDR content. Sony also announced at IFA that it will add HDR support to its entire 2015 Ultra HD TV line-up.
- “Samsung provides cutting-edge technology that our consumers expect from an industry leader, and our SUHD TV’s are our best ever” said John Ryu, vice president of the visual display business at Samsung Electronics.
- “While our 2015 SUHD and UHD TV lines are already capable of delivering HDR capability from internal sources such as streaming services, this firmware update will enlarge the spectrum of available HDR content for our customers.”
HDMI 2.0a will be supported by all 2015 SUHD and UHD TVs via a firmware update, says Samsung. You can use your existing HDMI cables.
So basically all 2015 Samsung sets can play HDR and quality is dependant on tv's capabilities .
Same goes for Sony
Sony Europe today announced that it is bringing High Dynamic Range (HDR) compatibility to more of its 4K Ultra HD televisions. In addition to the previously announced X94C and X93C series, Sony is also adding HDR compatibility to the X91C, X90C, X85C and S85C series via a network update. Sony is working with streaming video providers such as Amazon Video to bring customers movies and TV shows in HDR (High Dynamic Range), a premium technology which generates deeper blacks, brighter peaks, and richer colour tones.
