Fair point! I forgot about the initial trains' issues. My first ride was post-2010 admittedly. And, that profiling has NOT weathered well sadly. It's a really interesting coaster with a fun layout. But, it could use a reprofiling and song update desperately. (I have to imagine it's on Universal's list.)
For CR, I'm honestly much more concerned with the rotation mechanism, screens, etc. wearing out before track roughness. A bit issue it will deal with is image drift (meaning alignment between the cars, screens, etc.). One of the big contributors to motion sickness is misalignment between real motion and perceived motion. That's likely a much greater risk over time than the track profiling.
