Possible to determine significance in sensitivity analysis?

Yes.  If you have respondent level data, since share is a metric variable you can test using traditional statistics (e.g. a dependent t-test) or via Bayesian methods using the draws file.  These tests are described here https://www.sawtoothsoftware.com/169-support/technical-papers/cbc-related-papers/2033-statistical-testing.
