Thanks for sending the diagnostic logs.
Is this the actual diagnostic logs during display off status?
Does the display off happens immediately when the diagnostic script is running?
I thought it happens after a few minutes?
Could you also please try to update your Intel Graphics driver via Intel Support Assistant from this link:
Based on your logs, you have iOS Viewer app.
Is it possible to try with other viewer app? e.g. HTML5 viewer via web browser, or android if you have?
