Blu-ray's are encoded in 8 bit RGB/ 24 bit depth. Unless that has changed, there aren't any sources that are encoded in Deep Color. You can certainly upscale to 30 or 36 bit (as most newer blu-ray players can) and quite a few tv's can display Deep Color ( I know my 3 year old LG can) but all you're doing is adding information that isn't there in the first place. What can happen is you either get a very bad looking picture, or depending on the quality of the upscale, banding in the picture in a lot of cases. It's a feature that I wouldn't worry about or even use.
