It's always possible that your psychologist would update your report with the extended scaled score, but honestly unlikely. This has nothing to do with the "legacy" nature of your testing, as extended scores can be calculated as long as your original report included raw scores. It's more that the extended scale score would be reported in isolation. One doesn't commonly compute index scores based on extended scale scores unless multiple contributing scaled scores are 19+.
But if you really need to know...your FSIQ and CPI increase negligibly, and your AWMI rises very slightly more, remaining in the mid 140s.
The more interesting quantitative observation is that your AWMI (even standard scoring) is substantially higher than your other working memory task on the WISC (Picture Span-- 11, which could be presented as a standard score of 105). That's over 3 SD difference between AWMI and the remainder of the WMI, possibly a reflection of the visual aspects of the task, which connects to your WJ COG results, where spatial relations (visual spatial task) and visual-auditory learning (rebus task requiring attaching meaning/language to cartoon-like images) were both in this range as well. It appears you had either experienced additional brain maturation in this domain, or developed more effective compensatory strategies, or benefited from less visual memory load on the specific tasks--or most likely some combination of above--by the time you were retested five years later, as your WISC-V VSI rose quite a bit compared to the WJ SR test. Visual memory, however, did not.
