These look just as you would expect.

Viewed on an sRGB monitor with a non-color-managed viewer (irfanview), they are dull and desaturated. Viewed on a wide-gamut monitor with the same non-color-managed software, saturation looks normal.

Viewed simultaneously on an sRGB monitor and a wide-gamut monitor side by side ( by using a copy of the original TIFF) in color managed software (Photoshop) the colors generally look normally saturated in both cases, with the facial and hair tones matching.
For the doorman shot, the green of his epaulets, gloves, etc., is slightly yellower and desaturated on the sRGB monitor. The blue-green of his coat is slightly desaturated on the sRGB monitor. This is an indication that these two colors are outside the sRGB gamut as captured by your camera, while the skin and hair tones are inside sRGB.



If the doorman and a copy are both viewed on the wide gamut monitor in Photoshop but the copy's color profile is converted to sRGB, you see similar effects to viewing the copy in Photoshop on the sRGB monitor.

Summary: it looks like you are succeeding in showing what's on the 15GP22 if the end viewer has a wide-gamut monitor and color managed software.
