Too true.
As you say, the lighting is going to be too dynamic for a one-off on site WB to be useful.
But having an 18% grey swatch visible in every image I want to correct would solve that problem... Then I could just point the WB dropper in LR or PDCU at it to get my PP started with a decent and consistent WB reading.
I recognise (thanks to this thread) that the nature of LED lighting means that even if I get what appears to be a nice solid reading off an 18% grey tape or card, it may still not give me reliable enough colour information for WB correction, but I might get lucky sometimes.
I attended a gig recently where the band had a ring of grey(ish) taped labels around the base of all of their mics, and those labels worked OK as a target for my WB dropper. Hence my idea

Aha. So there are no 'pro' secrets to this, either in technique or hardware.
I often wondered if the big pro FF's like your Nikon D4's and D800's etc would do any better with their WB under LEDs than a mere K-x or K-5. Doesn't sound like they do.
