$User.UITheme and $User.UIThemeDisplayed do not respect the actual UI when the affected user was forced to be switched to Lightning Experience by profile level.
If UserPreferencesLightningExperiencePreferred of the user is false, these global variables don't return Theme4d. This is because $User.UIThemeDisplayed and $User.UITheme refer to UserPreferencesLightningExperiencePreferred field of User Object.

1. Create a custom profile by cloning Standard User profile

2. Create a user which uses the above custom profile
* The user is still using Aloha UI.

3. Create the following Visualforce page
<apex:page >
Enable "Available for Lightning Experience, Lightning Communities, and the mobile app" option

4. Add the above custom profile to Enabled Profiles of the above Visualforce page

5. Create a Visualofrce tab of Content of above Visualforce page from (3)

6. Enable Lightning Experience

7. Enable "Hide Option to Switch to Salesforce Classic" perm of the above custom profile

8. Login as the above user which was created in Step 2
You will see Lightning Experience.

9. Go to Visualforce tab from App Launcher

Expected Results


Update UserPreferencesLightningExperiencePreferred of the affected user to true by Apex code/API
