The biggest differences are white balance, mixed lighting, and exposure control.

Your scene appears to have different light sources with different color temperatures, so Auto WB can easily give inconsistent or overly warm results. If you shoot RAW, you can correct white balance later much more effectively.

The reference image also looks like it used controlled added light, not just ambient room lighting. Extra lighting lets the photographer use a shorter shutter speed, which helps prevent the lamps from blowing out and gives cleaner, more balanced color.

To get closer:

• Shoot RAW.
• Set or correct white balance carefully in post.
• Reduce clipping in the light fixtures by exposing more conservatively.
• If needed, use multiple exposures/HDR subtly so bright fixtures and darker areas both retain detail.
• In post, you may need selective color adjustments (especially yellows/reds) if the stair lighting is a different color than the rest of the room.

If the room lighting itself is mixed, perfect color everywhere may be impossible without changing or adding light.
