Short answer, right now, soul sparkle is known to be dominant to Tapestry Allure, and so yes, it is also dominant to crystal berry and strawberry bellini.
There are several places to check the answer for that kind of question.
1) Most people check the Saga Charts.
SAGA Eye chart
Nothing is posted in SAGA without proofs that have been through several layers of vetting. New traits for which there is a large range (such as soul sparkle) are listed at the very bottom of the chart.
2) There is a more recent option called KittyCats Proofs. The aim here is to get information fast from the forum and up and online quickly. The proofs are here on the forum, so you can vet them and others can vet them for yourselves.

3) Check out the thread in the breeding section of this forum which is dedicated to your trait.
Index of Traits. That will give you the run down on all the testing being done (that has been reported) for your trait of interest.
If you need help reading the dominance charts, let me - or really any of many helpful breeders on this forum and at Saga - know. We are happy to help.
