Sakumo I haven’t noticed any change in HDR yet. Probably the changes apply only in a very certain scenario.
There was a bug where when focusing on a dark-toned subject/object in scenarios with insufficient lighting, the HDR was activated and went crazy, over-processing the image, giving a ‘hyper dramatic’ effect to the subject/object, raising its contrast to the maximum and overilluminating the rest of the pic.
That is normally the main scenario where it occurred in my experience. I could notice it especially because I have a dog with black fur and when taking close photos of him in my room (without too much lighting, just an LED bulb) that happened.
