Based on what it did to the dotcrawl, which can be quite expensive to encode and the massive boost to over-all temporal stability from TGMC, I would be much more surprised if there wasn't a large difference in file size.
A more apples to apples comparison might be denoising the other bobbers with mvtools and then checking their file sizes, though that isn't a very realistic usage scenario, pretty much everyone would just use TGMC in such a situation (or rather, they should). I suppose for speed purposes actual usage might look like hardwarebob->fft3dGPU, which is no longer directly analogous to TGMC qualitatively (almost purely spatial vs almost purely temporal processing, everyone knows how that ends).
