I wonder why that was? Was it because the FM carrier was deviated toward the high end on yellow and starting to approach the end of the heads' frequency response?

I think that is exactly it: the FM deviation extreme for video tape recording composite video was yellow. If the heads were worn, yellow would show the speckly drop out most noticeably in yellow first.
I recall however for 1970's studio cameras using plumbicon tubes, the noisiest color was blue. I think this was because blue is low luma and at the low (expanded) end of the gamma curve.
