"allowedValues" of "Get edit issue metadata" service response

We are using “Get edit issue metadata” service (https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issues/#api-rest-api-3-issue-issueidorkey-editmeta-get) to check whether user can edit some field and to obtain the list of possible values for field (“allowedValues” field in response).
Our question here, is this guaranteed that “allowedValues” field contains all possible values for field? Can the service return only part of possible values (paging)?
