Did you watch any of the BBC iPlayer 4K HLG HDR footage for the Euros in the summer? Have you experienced any BT Sport Ultimate in 4K HDR10 50fps? If so, how have you found that?I have had my 75XD9405 professionally calibrated for HDR. On this model, you can't change picture modes once it receives a HDR signal, it just says "HDR VIDEO" People on the forum are using ACE and upping the gamma to max to try and brighten the picture which I don't really want to do. Like I mentioned, downloaded programmes in HDR HLG look great, just not the football. Admittedly, my TV is a 2016 model, but I believe it was Sony's flagship LED for about 5 minutes before the ZD9 came on the market.
