While I had the motor out last month I replaced my clutch disk.
My pressure plate looked better than yours at 44k or so, but my disk looked just like yours with the center plate and marcel springs badly overheated and purple.
Did you mic the disk to see how much wear there was? (Measure the depth of the surface at one of the rivets - brand new it should be about 1mm; the wear limit is .3mm. Mine was about .2mm.)

I've read that that area on the stock units is purple straight from the factory, and shops just point to it as "evidence of overheating". Not true?
If anything, I'd suspect that the blue areas saw more heat. The purple is near the bolt holes and the shaft -- places where heat would be sinked away.
Another question that comes to mind is the issue of "bedding". Seems to make sense for brakes. I wonder if a similar benefit could be had for clutch? After all it's similar interface -- friction material against a steel face.
Would take a lot more bravery to get the clutch smoking on a brand new car than doing the brake pads though. But, could be done in a driveway

I used to have a friend that run his own performance shop. He did mild hondas/toyotas to $$$$ people spending 20K+ on a motor. He moved away to a better area, but he was strongly for ACT clutches and he tried to make everyone that wanted a swap to buy them.
And no he wasn't doing it to make money, he could get them for you if your lazy, but he'd rather you shop for the best price then bring it in.
