Picked up an 65MU8500 this past weekend (apparently the successor to the KS)
Any word on if game mode HDR is having issues with this model, as well?
It has the same problem as the KS models with not having separate settings for HDR-enabled games, forcing you to adjust settings manually between the two. This problem will supposedly be fixed with an update soon:
2017 models (Kant M, MU) : Oct 12
2016 models (Jazz M, KS) : Nov 27
