I don’t understand why you stopped publishing the results just when the “normal usage” tv was beginning to have burn in. My normal usage is the tv on for 16 hours a day watching tv shows, films old b&w shows/films some with letterbox on UK terrestrial, Netflix, Prime, Sky. Very little news or sports. So the period you have covered would represent 3 years to me. Any chance you have up to date results as I am about to buy a new tv and would like OLED but concerned about burn in.
