Short answer
A sunset is a hard scene for a camera: a huge brightness range, light that is itself strongly coloured, and saturated oranges and reds that clip one channel early. Depending on choices the camera makes, the result goes either way. Auto white balance may neutralise the warm light and drain the colour; tone mapping and saturation boosts may push it beyond what you saw. Your eye, meanwhile, adapts to the warm light and compresses the range in ways the photo does not.
At sunset, sunlight crosses far more atmosphere to reach you. Short wavelengths are scattered out of the direct beam along the way, which is the same scattering that makes the daytime sky blue, so the direct light is depleted of blue and looks yellow, orange or red; dust and aerosols deepen and redden it further. The whole scene is lit by that light, and the sky around the sun is bright and saturated while the landscape is in deep shadow. For a camera that combination is the worst case: an extreme range of brightness, a strongly coloured illuminant and saturated colours all at once.
Auto white balance is built to remove colour casts, and a sunset is a colour cast from edge to edge. If the algorithm treats the warm light as something to correct, it pulls the whole scene towards neutral and the orange drains out. Many cameras recognise this and hold back, but not always. Separately, exposing for the bright sky leaves the land black; exposing for the land clips the sky. Your eye handles both by looking around and adapting; a single frame cannot.
Setting white balance to a daylight preset rather than auto keeps the warmth you saw.
Other pipelines push the other way. Multi-frame merging and local tone mapping can lift a dark foreground and hold the bright sky, producing an image with more detail everywhere than the eye perceived at once. A contrast curve adds saturation in the midtones, and the hue-specific tuning some phones apply to skies can shift purples and cyans towards cleaner blues. Where the red channel clips on the brightest clouds, hue shifts towards orange-yellow and gradation collapses into flat bands. Viewed later indoors, without the adaptation state you had at the time, the result reads as more intense than memory.
Fix white balance at a daylight setting so the camera does not neutralise the light. Expose for the brightest part of the sky you care about and check the red channel histogram. If you want the foreground as well, use a burst or bracketed exposures, or accept a silhouette. In editing, adjust saturation last and compare against your memory of the scene rather than against other sunset photographs, which are often edited for effect.
Each statement is labelled by kind — established fact, a standard’s requirement, observed market data, a convention, or Colourwise’s own interpretation or analysis — with the strength of the evidence behind it.
FactStrong evidence
Rayleigh scattering by air molecules scatters short wavelengths more strongly, which colours the daytime sky blue and depletes the direct beam of blue when sunlight crosses a long path through the atmosphere.
FactStrong evidence
HDR+ was designed for scenes with a wide range of brightness, explicitly including sunsets and backlit portraits, and brightens shadows while preserving local contrast.

FactModerate evidence
Auto white balance compensates for the dominant colour of the illumination, so a scene lit entirely by warm light risks being partly neutralised.
Colourwise interpretationLimited evidence
Whether a sunset photo looks exaggerated or dull depends mostly on white balance and tone-mapping choices rather than the sensor.

Caveat: Clipping at the sensor also contributes, especially near the sun.
