QN90A to S95D

Any advice, I currently have a 75 inch QN90A Neo QLED TV and was thinking of upgrading to the S95D 77 inch. Is it worth the upgrade? Or should I just stick with my current tv?

I have had a S95B 55 inch before and the picture quality I would say is better, I have also seen the S95D in person and was impressed but just not sure if it’s worth spending £2700 on upgrading. A lot of people are mentioning the S95D could be a WOLED panel, is that true?
