Well, considering the DVDs are objectively inferior in every possible sense compared to the Blu-rays, that's a pretty drastic thing to resort to... and so there's something either fundamentally wrong with your setup or your expectations. The film stock was actually in very good condition and it was not scanned at too high a resolution. I don't mean this as condescending, but I assume you're hooked up via HDMI and not analog component cables, right? Have you calibrated your display -- at all? You're not viewing the episodes in a "dynamic" or "vivid" mode are you? If so, that could be unnaturally brightening the image and boosting the colors. Also, your sharpness should be set very, very low. You should not be artificially sharpening the image, that can make everything (particularly the grain) look very, very bad. And definitely turn off any DNR. If your display is uncalibrated, start with a "movie" or "cinema" mode and tweak from there, based on the lighting conditions you're viewing the display in. That kind of a mode should be closest to a 6500 Kelvin or D65 reference color and have the best black levels. If you have a Blu-ray with a THX Optimizer, that would be better than nothing to calibrate with. They also have a free iPhone app that you can use called THX tune-up.
