I've had my QN65Q80 for around a year now and HDR content is forced-on (when available) for content in the Amazon Prime app. HDR content is unbearable, unnecessary, and looks downright terrible. Whites are blown out, blacks/grays are washed out, the brightness is dim, and color reproduction is horribly inaccurate. However, all normal content looks fantastic and the TV is plenty bright. I don't see a way to disable HDR and haven't found a solution online.
Are there any methods to disable HDR on a Q80? I'd rather not buy another Roku just to circumvent this.
