Had put some swatches on the wall previously in an array of colors. Now picked a final color and put some primer over so that there would not be variances due to the colors underneath, but the area where the primer was places now has an extra sheen to it with the top coat.
Any tips from pros on how to correct? Am I going to have to prime the whole wall now and re-paint my top color?

Did you prime the whole wall or just the places where your test colors were?
Like Piffin said, the problem is not the primer per se, the problem is that you only used 1 coat. The areas that were primed are less porous than those that weren't so the the topcoat is acheiving its ultimate (and intended) sheen in those areas. Everywhere else needs a second coat.
The purpose of the primer (when priming over paint) is not so much for color uniformity as it is for porosity uniformity.
Just primed the area where the swatches were - some were dark, some were light. final color is dark...
Going to do another coat on the shiny area to see if it makes a difference.
spot priming only was your problem.
Another full coat of finish should make things right now. But for 100% right, prime it all, then repaiont
Unfortunately, TV shows and now paint commercials show folks trying out paint colors by painting patches on their walls. Don't do this. Use some large scraps of drywall and hold them up. Covering over those patches can be a big problem, it's not just the color but the texture. In some cases, you may need to spot prime over the patches with a stain blocking primer, pigmented shellac or Kilz, then the entire wall is covered with a regular primer, then two coats of the color. Primers can be tinted for better coverage but trying to hide painted patches may take more than two top coats.
Yeah, and if you really MUST paint your samples onto the wall, don't give the samples sharp edges with masking tape -- let the edges blend out into the rest of the wall a bit. Otherwise the edges will show through, even after 3-4 coats of paint.
Just use poster board
My wife actually taught me this trick. Apply the paint to pieces of poster board. Then you can tape the posters to the wall or move the poster board around to different areas (lighting differences etc). We also hold onto them for use later for common colors. We write the paint numbers on the back.
paint sheen
I had problem like it when I painted with Behr paint+primer (which I later found was called Flat enamel) over Kilz 2 water base primer. In addition, the paint color can not be matched between regular flat paint and combination flat enamel paint. I had to prime the whole room and repaint.
