I don't think so.The "normal" configuration for sub streams is to use a very low resolution for the sub stream, like D1, and I set a CBR that gives me a reasonable picture. Apparently, you have the sub and main streams set to the same resolutions. Be aware that you will need to re-configure motin dtetecion for cameras using the sub stream since the resolution change effects the overall view for detection.
In the list you provided, cameras 2, 4, 5, 7, 8, 9 and others show the same MP as the main stream. First column shows 4.1/4.1 on second camera. Not sure what you have there, but that is what it is showing.
If I use that whole path it errors so if I just use "/cam/realmonitor?channel=1&subtype=1" it works.Here's some help for you. This is a 5442T-AS and is listed as Front Yard East in the status capture -

The pulldown just shows none and default.Change sub from (default) to something with "substream1" in it.
That is a pulldown menu item.
I think you are typing that in? It is a PULLDOWN selection if it is working properly. Follow @sebastiantombs post above.If I use that whole path it errors so if I just use "/cam/realmonitor?channel=1&subtype=1" it works.
