RGBA4444 using more memory than RGBA8888?

We've been looking for some ways to cut the memory usage of our 2D canvas game and thought we'd try converting our PNG files to 4-bit from 8-bit using TexturePacker. TexturePacker shows half the RAM usage during this conversion (exporting as RGBA4444 instead of RGBA8888), but when we load the game we seeing ~100MB increase in process memory in Chrome. This seems rather counter-intuitive as I assumed worst-case it would use roughly the same memory. Any ideas what could be going on here?
