3D and 4K were nothing! It's all about HDR now!
Netflix has confirmed it has begun its rollout of high dynamic range content on its TV and film streaming service. HDR videos display millions more shades of colour and extra levels of brightness than normal ones, allowing images to look more realistic.
However, to view them members will need a new type of TV or monitor and a premium-priced Netflix subscription. Some HDR content had already been available via Amazon's rival Instant Video service. Ultra-high-definition 4K Blu-ray discs - which launched in the UK earlier this week - also include HDR data.
Netflix's support follows January's creation of a scheme defining the HDR standards a television set must meet to be marketed with an "Ultra HD Premium" sticker. [...] The US firm recommends its members have at least a 25 megabits per second connection to view them.

We have been using HDR (or equiv) for years in the sciences - our microscopes produce images in 30 bit tiffs, though resolution has improved. Gimp can handle 30 bit images, which is handy for my AFM data!!

I'm not sure color depth is the same thing. For example, 10-bit color (~1.07 billion colors) has been around in consumer hardware and codecs for a while now (for example, HEVC Main 10 profile), but the Wikipedia article mentions HDR10 Media Profile, which combines HDR and 10-bit. If it adds some brightness channel, it would be more than 30 bits per pixel...

well "colour" is wavelengths so , yes it is equivalent. In microscopy the lamps (mercury etc) the filters set colour and luminance measured for each band. With laser confocal, you get narrow colour, very deep luminance as laser spread is so minimal at those distance. Electron microscopy is *phenomenally* precise, as you are counting electrons.....think about that!!! You can get individual elements from atoms under STEM - exceedingly cool.
With AFM it is a mathematical description of force/current and other derivatives, which are pA sensitive (10^-12). By now, might even be 10^-15 A as I did this 5 years back, with equipment probably 5 years old!! So we have the TIFF format which is probably the only standard - every instrument has it own "special" junk format....
Human eyes (for some biology) have very deep colour perception, but pretty lousy resolution which is probably why this has been late coming to market - linear resolution is just more of the same, but deeper (bit width) needs much greater increases in computational power.
To get more information we often process many slices to produce a composite and exploit 3D/parallax. I fully expect the VR headsets to get updated at some point, though TV's are of course more widespread.
The VR revolution might really help in scientific viz, and I say that as a flicky glasses veteran.....
