We work in a Rec 709 color space so the pixels are the same as they are in HD. The Quad HD output of 4 individual HDSDI quadrants respect the proper levels without the added over shoots that cause RGB gamut errors.
My understanding is 4K did nothing to improve the pixels with more color space. I realize HDR and other variants are different in that respect but given I'm in an entirely Rec 709 space I don't think that applies. If the 4 separate quadrant signal showed the same gamut error then I would be more inclined to agree.
Have I been wrong thinking 4K is more but not better pixels? That seemed to be the typical thought I've heard. The delivery specs list Rec 709 so that's what I deliver. I'd appreciate more info regarding what the 4K UHD standard spec is and how additional color spaces are being utilized. I see some googling in my future.

You can't monitor a UHD color space in HD
You'd need to have LUT box downstream of the HD output and even then it wouldn't be accurate.
