You may not find a cure outside of making it a reason to return for another model.
There was a new firmware pushed to this set recently. It included settings for gamma and input lag, which was previously not present.
I'm looking for settings belonging to this specific set, not the M line in general, that includes updated settings for gamma.

I would really appreciate this.
The generalized settings for the M line destroyed black levels, I'm convinced from seeing other M sets that what's posted isn't a cure-all.
