P: Add 10-bit/channel color display support

I'm pretty sure that LR uses a 16-bit internal workspace, while the display is only 8-bits, so the term 8-bit-processing isn't quite right. 

My Nikon D3 produces RAWs with 14-bit color depth.  With 8-bit processing in LR, I'm throwing away 6 bits of color depth smoothness and gradation.  As others have pointed out, Photoshop has 10-bit color support, so it's not something that Adobe can't do. And nowadays, both Windows and OS X support 10-bit color.

Having just tested 10 bit support in video media with a good - but not ridiculous - rig and seen the difference it makes I am very keen to get 10 bit support on ALL my photo apps.

windows 10 - nvidia 980ti - Dell U2713H. I know this monitor is doing slightly fake 10  bit (as many laptops do fake 8 bit), but the improvement is significant.

we, photographers, need Lightroom to support 10-bit display output for having our advance displays like models from Eizo or NEC producing 10-bit billion color depth

I am a very satisfied Lightroom user, but the lack of 30 bit color display capability it's a major shortcoming for a pro grade software.
I hope this feature will be added soon.

I fully understand that you can't give Lightroom too many of the attributes that Photoshop has but a 10 Bit Monitor is just superb [using PSCC] and dare I say the defacto standard for sill digital image editing. It would be really nice to see Lightroom 6 having the same facility. It would also give the two Applications greater synergy when viewing/editing.

Thanks... yes, you already mentioned that here, too: http://feedback.photoshop.com/photosh... ... But I seem to have overlooked it, or simply forgotten ;-)

So... is it safe to assume that because of this, LR does not really need 10 bit output? I mean, if the dithering works so well on artificial images, it should work nearly perfectly on most real world photos. The only case when 10 bit would have an advantage is when there are sublte tonal *patterns* (e.g. fabrics, etc.) with small size (some pixels), which cannot be shown using dithering. But I doubt that such patterns can really be seen even with 10 bit.

Yes, Develop and Export (to 8 bpp) dithers.

Additional question: Does LR use dithering in the develop module? I just loaded the 10 bit test ramp from http://www.imagescience.com.au/kb/que... into Photoshop and LR (8 bit output). In Photoshop, I see the 8-bit-banding, as well as in LR loupe (because previews are 8 bit JPEGs). But in LR develop, there is no visible banding!

This would be actually great, because it is the next best thing to 10 it support.

Edit: Yes, LR develop really seems to use dithering. Here is a small portion of the ramp, with extremly amplified contrast (screenshot from develop module, contrast amplified in PS):
