Bad HDR is a bit of a plague within the budget tv landscape. It usually makes things worse and not better if your TV can't reach 400 nits at minimum, and on some sets it's just outright bad. Worse, Smart TV functions will use those HDR settings and, in most cases, give you no chance to turn that bad HDR off when the SDR picture is outright better. In a lot of cases, you need a streaming box with its own internal setting to enable or disable HDR in order to get around it.
The whole experience gives HDR a bad reputation and makes consumers get headaches all because manufacturers crunched the numbers and knew they had to sell the TV with a big HDR logo on the box to be competitive.
