I've searched Dr. Darbee's posts and the closest response I can find to the 4:4:4 /4:2:2 issue is this response:

Another way to put the answer is this:
The HDMI 1.4 spec demands 165 MHz for 1080p/60fps, or put another way, allows 165,000,000 ops/sec.
Since we pass a (10bit/color channel) pixel to the output within this specification, we are putting pixels (first in, first out) across our circuit with a total latency of 3 microseconds.
The latency is inconsequential for any human factors of perception for image or audio, even for video gaming.
Hello DD. My setup is OPPO BDP-95 to Kuro 141FD using HD Base-T hdmi over cat 6 Beldin Mediatwist. this allows me to utilize the 12bit pixel depth Deep Color setting on the OPPO and Kuro.
will this present a problem using the Darbee Darblet since it only passes a 10 bit output?
Here is the response from our engineer:
"This should not be an issue. The Darblet will accept the 12-bit input, reduce it to 10-bit internally, and then after processing kick the signal back up to 12-bit for output. This means that, when Darbee is OFF, the output will not _exactly_ match the input signal, but the difference will of course imperceptible."
I don't believe this implies that the Darbee processes internally at RGB - anyone else have any info on this question?
