I recently noticed that my 'new' to me corvette has a dimmer passenger fog lamp then the driver (looks a bit silly for such a nice car ).

I figured that the previous owner did not replace in pairs and went and purchased the ultra bright bulb this weekend. I replaced both and still have a bit of a dim look -- I would describe the driver's side as very bright with a prism effect; the passenger side being a bit brighter then the original, however no prism...

The fixtures both appear to be original, as well as the lenses. Is this an electrical issue / loss in ground / ????

Any suggestions

Bet you've got a bad ground on the dim fog light. Remove, clean and re-attach. Do not use a star washer.(source of corrosion)

Are the bulbs identical? Before I would go off chasing wires, I would make sure that I'm comparing apples to apples. I would even go as far as to replace both bulbs with identical bulbs.

One cheap mod is to replace the stock 37 watt bulbs (with a black end) with 50 watt bulbs (with a clear bulb) (855) and re-aim them, it makes a world of difference.

Check, maybe someone replaced just one with the brighter bulb.

I replaced both bulbs this weekend with identical bulbs. the passenger definately has an issue.

About that wire chasing and cleaning... any more details?

Well, here's a starting point.

One thing you can try real quick is to splice the bad light's ground into the good light's ground. Just take a wire and connect it to both points. If the dull light brightens, then you know it's a ground issue.
