If you're the inventive hobby type I'd love to see you run a little experiment - get or make a small wooden or metal box, install a standard lamp light bulb fixture on the top or side, get a thermometer, and run an elevated heat oxidation test on V and GV. You'll need to fiddle with the bulb size, you want the temp inside to be 100 F - 125 F - a dimmer switch with a 75 watt light bulb would work best. Find the right settings to keep the inside of the box at a constant temp and let it run for a month, then take the caps out, split them open, and do the smell test - if the GV smells even worse after this high temp test but V doesn't it will prove that the GV is more prone to oxidation over time at room temps, either because of what's inside the cap along with the EPA or because of the capsule shell composition, which AMRN has patented. I could easily do this myself if I had some GV, right up my alley.
