Thank you for reaching out to the Samsung community! We would like to inform you that Blue light filter helps to reduce eye strain by limiting the amount of blue light emitted by the screen. While you are watching HDR videos from HDR-exclusive video services, the blue light filter may not be applied.
1- On the Settings screen, tap Display → Blue light filter, and then tap the Turn on now switch to activate it. 2- Drag the adjustment bar to adjust the filter’s opacity.
