if you unplug and remove the bike does the trainer move smoothly? on my old kicker i could grab the flywheel and spin it easily. when doing that it should come to a stop and rotate in reverse for a degree or two. sort of like back emf in a motor dissipating.
It spins smoothly with the bike off/unplugged.
The issue started when I did the old manual calibration - immediately. This is why I think its software.
I took the bike off last night, got it out on the road for the first time in a few months (been riding a different bike on the road) - and at 20mph it was a breeze to ride. It used to be 20mph on the road was harder than 20mph on zwift, now it's flipped. That bike is in the shop now for a tune up, when I get it back I will put my power pedals on it and compare to the trainer reading.
My RPE and HR being the same, I now average .5-.75 wkg less on the trainer than I did before the calibration.
IMHO it's 100% software/firmware. The power meter will tell the story.
