Warping is actually from pad material being stuck to the rotor in uneven spots, not the actual warping of the rotor. You come to a stop with your foot on the brakes and the rotors are hot and while you sit there with the pads clamping the really hot disc, pad material sticks and you get warping.
In my experience with these cars the OEM rotors or at least the rotor/pad combo is prone to warping. Replacing the brakes with centric rotors and centric ceramic pads did away with the issue, but the OEM brakes always warped within 10k miles for me.

Warping is not an "industry accepted" term it's constantly parroted ad nauseam, incorrectly. Warping means warping not pad material fusing to the rotor. A cylinder head warps, a rotor does not except under extreme conditions which will never happen on a street car.
For anyone doing brake work a took like this is essential

Arguing about what this should be called doesn't help the OP.

The OP has the base car so any discussion of the F Sport wouldn’t make sense.

I'm saying those are below mid level rotors. These are mid level rotors.

Maybe it's me. I am ready to hear that.
But for like 4 sets of rotors now, I get between 12 to 18 months before the dreaded warping come back. Is it me, or does anyone else experience this. I will admit, I drive fast on the highway, but I'm like a little old lady on local roads. ONE time, I totally know what happened as I drove into a puddle in front of my house and the steam coming off the rotors was A LOT. Next day, warped.
I've tried OEM, Centric and whatever brand my mechanic gets... probably Raybestos or similar. They replaced the rotors under warranty at about 4 months. But then those replacements warped in like 6 months, and I tried the Centric. Those lasted the longest, at about 18 months, but now as soon as they heat up a little the "massage" begins. I pretty much know when it happened there too. I was doing about 85-90 and had to slam on the brakes hard. That one incident warped them.
I never had this issue with my LS430 which is still being driven by my daughter and still has silky smooth brakes.

Stock S8/W12 brakes are 400mm floaters, optional are CCBs. You have 380mm below that for all V8 cars, then 365s on some euro specs and 330mm for V6 and hybrid cars.
So yeah, 380mm is the mid level brakes. Lexus extreme top end stops there.
