Does anyone else have HDR issues?

The screen doesn't support HDR videos. The brightness slider stops halfway, and even my old Huawei mate 20 pro gets way brighter. Non HDR videos are fine, and get really bright as intended. But HDR videos do not work whatsoever. I have tried different streaming apps (Netflix, Hbo, YouTube) but nothing works. Reached out to Samsung couple months ago, and they said that a technician will reach out. But so far, nothing from them.
