I currently have the LG 24UD58 4K monitor, i7 7700K and GTX 1080.
Why can I only watch Netflix in 4K when I connect to HDMI? When I switch to DisplayPort 1.2, it removes the "Ultra HD 4K" tag NetFlix puts on movies and TV shows when you have a 4K screen, and I can only stream at a maximum of 6000~ MBPS on it. On HDMI it shows the Ultra HD tag and allows me to stream at 16,000 MBPS.

I can't find any info regarding why this happens, but I would rather use DisplayPort as to me the colors look more vibrant and the black levels are darker on it compared to HDMI.
 
No, you need to set it to 8 bpc RGB so that it allows you to change the output dynamic range, which needs to be "Full" rather than "Limited". Using YCbCr is what causes the image to be washed out.

NVIDIA Control Panel -> Change Resolution -> bottom section
