Backlight and Brightness set to 50. Dark room. The bloom is definitely there in some scenes, but not much visible to my eye unless i am looking for it and near the tv. And the cell phone camera captures it at ~100x more intensity than what i see with naked eye. So dont go based on the pictures you see on the internet, and think thats how good or bad it will look like in person.
Below are the videos i played, to capture the pics.
There will be positive and negative for oled and qled. Other than that, if you are looking for a 75 inch experience, in the budget segment, this tv is very good for an average person who is focused on content being watched.
If you are an enthusiast and picky about details and perfection, you may or may not be satisfied with this tv based on your personal preferences with colours, black levels, ambient lighting performance ,size etc.
