In my haste to make air I read the delivery of "ProRes" to mean ProResHQ. I have never really scrutinized ProResHQ vs. ProRes 422. I now know that they are both 422 but HQ is like 220X and ProRes 422 is like DNX145. We shoot a show on Alexa and edit in 175X. Why would the network want me to down grade the image to ProRes 422 instead of HQ. They have agreed to accept the file but is space more important than quality? Perhaps for on air it's a negligible difference but really for a few GB of space this big 3 network sacrifices quality.
I offer:
The Today Show went from DNxHD145 to Sony XDCAM50 two years ago because the file space required is TWO THIRDS less, yet the quality difference is not discernible (I know I can't tell the difference in quality and I look at this stuff every day). Storage space is very important to the network. Though the difference between DNxHD145 and 220 may be negligible to you, the number of programs they must process adds up to a lot of data. They've made their choice to go with DNxHD145 quality on-air.
