Does shutter speed affect image quality?

I know that to get a great exposure you need to match the shutter speed to the aperture.....these facts are self evident. But does exposing the sensor to a longer (or shorter) period of time actually affect the IQ? I always wondered since some of my shots taken with different exposure times seem to look better than others even though the focus, exposure, ISO and lighting are exactly the same. I understand that different apertures yield different results but I am thinking more along the lines of color saturation and overall curb appeal of the final image. I notice the difference mostly when shooting in the studio under controlled lighting. Anybody else notice this or am I the only one? Thanks for any input!

You say " I notice the difference mostly when shooting in the studio under controlled lighting", what is it that you notice? Do you have sample images that demonstrate this?

The "base" exposure of the shutter speed combined with the aperture opening should deliver an equivalent image, but then I'm not an optical scientist or image scientist who can break down all the "bits and pieces".

But I don't think any quality differences you think may be there are likely due to one shot having a slower shutter speed/narrower aperture except for the differences that can happen if, say, you mishandle the slower shutter speed or, in the other case, mishandle a wide aperture.

I can't really put my finger on the differences but some images just seem to POP more than others even when shot in similar lighting conditions. It may just be my opinion about the difference in IQ too as other people don't seem to notice much. I was just wondering if anybody else had any experience with this phenomenon.
