I know iPhones have a color-tint setting that can make the display noticeably redder. My Samsung smart TV has a red-to-blue tint adjustment, but even at its strongest setting the effect is barely visible. Is there another picture, accessibility, or color-setting option that can apply a deeper red tint and reduce the amount of blue light, especially for watching at night?

The amount of blue light from a TV is much lower than what your eyes receive outdoors during the day. If the goal is better sleep, reducing screen brightness and avoiding TV shortly before bed is likely more useful than trying to completely remove blue light. Samsung models vary, but check Picture Mode, Expert Settings, Color Tone, and any Eye Comfort or accessibility options.
If the built-in tint control barely changes the image, the TV may not support a stronger system-wide red filter. You could try Warm or Warm2 for the color tone, lower the backlight and brightness, and enable a nighttime or eye-comfort mode if your model includes one. An external filter would be the only way to create a much stronger physical tint.
Blue light from screens is generally not considered harmful to the eyes, although bright screens can contribute to eye strain and may affect sleep if used late at night. A warmer picture mode, lower backlight, reduced brightness, and a dimly lit room may be more comfortable than applying a heavy red tint.
