The rotors have a specified thickness that they can be turned down and still
work fine. It is usually stamped on the rotor and is a common practice.
Turning them makes them flat again and consistent. They would not be
thicker in one place and thinner in another..
Granted, they can be safely painted, but Brembo and Stillen do not just
spray paint on the pistons and seals as you likely did. In that case, paint
is a very bad thing.

Nobody told me that, it is basic physics. If the rotors were scored, metal
would removed from the high areas leaving the rotor an even thickness
because scoring had already removed metal creating the low places.
In warping, no metal has been removed, the high areas were created by some
of the metal stretching and being deformed with relation to the hub. Turning
them would remove metal from the high areas and so they would be thinner
than the low because the vented backside of each brake surface would not be
altered - it is still warped. They would be uniformly flat/even, but not a
uniform thickness. Metal of varying thickness will heat and disapate heat
unevenly.
The real question is to what extent, and I don't have an answer for that.
The paint was specifically designed for calipers (well, rebottled high-temp
paint specifically for calipers). Both Brembo and Stillen make high-end
brake calipers that come painted, so I don't think that paint is always
evil.

Geeezz dude. If you turn them, that removes the high spots and puts them
back to a uniform thickness. They will not be thin and thick...who told you
that?
Spend all you like, its your money. You can get super duper setups, but if
you PAINT the calipers...expect problems.
Reman oem stuff works damn good, UNPAINTED.
