Nah. I wouldn't upgrade just for the red screen. As you say, there's more functionality to Pro which would make it a worthwhile upgrade.
Would be interesting to see how it works linked to the EQ6 and SynScan.
But I stand by my original whinge that red screen should be a basic "foundation" feature included in all generations of SN
I'll be sticking some red cellophane on the screen in the interim
