Cloud Kicks (CK) recently implemented Einstein Opportunity Scoring in its production org.

In Einstein Opportunity Scoring, if a user lacks access to a field (such as the Amount field) that is used as a contributing factor, that field is omitted from the scoring details that the user sees. Salesforce respects field-level security settings, so users without permission to view certain fields will not see those fields in the contributing factors section. Instead, the scoring model will still display, but without the restricted fields in the breakdown of contributing factors.
