You can test by plugging into an external Display and compare your results, this would be telling— if no issue externally it would indicate a display assembly issue. If the external shows the same fault it would indicate a GPU issue.


In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment

Make an appointment for a "hardware issue"—
