If you take a non-disadvantaged student with IQ GE 130, enrolled in 4th grade, and give them a standardized test on 4th-grade material, then you can expect them to score in the 95th percentile or higher when no gifted services are being offered. If offered, there isn't much growth to be gained, according to this particular measure. So, where are the gains to be noted for this cohort?

The gains are to be noted when age is factored in, and you find that the student is 7 or 8 years old. The gains are to be noted when tested on material at 5th-grade level or higher.
