I've been looking for tech specs on the Connect Spark Pro as it relates to 4k encoding and color depth.

Seeing as it only has a gigabit Ethernet It has to compress 4kp60 down to < 1gbit. But what is the approximate range (i know it varies).

I seem to remember using a PC doing NDI it would be at about 800Mbit? 1080p is about 1/4 that.

Also does it support 4:4:4 color depth or something less like 4:2:2, or 4:2:0?
