Yes that's the point of an Abbe value but if your lenses are super thin you can't tell. Chromatic abberation becomes more apparent as the lens thickness increases. Glass has the lowest but it's irrelevant if you're making glass an inch thick for example. No matter what you use, you'll have very noticeable abberation. The tradeoff for a thicker lens using 1.53 vs 1.74 will never be worth it as you'll be wearing coke bottles and you'll still see abberation because it's so damn thick.
