A good framework would have been this: for the options you received, let's see what you did. Did you trade them 3 years later, resulting in $X amount? Then, let's assume you would have done the same with the missing stock options. I would guess that the amount would be really negligible - in the tens or hundreds of thousands, at most. Ethically, I think this is where I would consider it fair to both parties.

Then, you neglected this for ~30 years. It's fair to say that Nvidia doesn't owe you anything at this point.
