If it is simply a higher quality CD then it will presumably track more precisely (less laser adjustments) and may also have less read errors that require correcting or in the worst case of a total inability to error correct - simple interpolation. In theory this will have no affect on jitter unless the activities of the transport mechanism servos are inducing jitter onto the DAC (via the powersupply rails or through EM/RF). Since induced jitter is more common in cheaper CD players perhaps this could result in an improvement for those players.
