^ Yes - a 10 to 15 point difference between CRAs is rather common on Fico 8 and Fico 9 even in cases where the account data is identical. After all, the Fico algorithms are customized to each CRA.
Older Fico models such as Fico 04 and Fico 98 accomodated higher levels of customization. As a result, scores among CRAs with identical profile data could vary by 50 to 60 points. I saw a +50 point difference between EQ and TU/EX when all my cards reported balances. EQ score was lower than the others.
