Well, the color and contrast look amazing already!

However, I did notice some quite noticeable light streaking on the far right side of the frame almost throughout the entire sample:

Is this present on the film or did it get introduced in the scanning process?

These artifacts are not part of the film print and were introduced by the acquisition device, in this case a DSLR camera.

It is called “CMOS SMEARING” and it happens on very bright areas of a CMOS captured image.

Some cameras are better than others but in this case it’s pretty bad unfortunately.
