IIRC TDM plugins are not int, they are 48bit fixedpoint. The gain wouldn't
be from not converting to float at every i/o it would be in the data not
leaving the DSP processor at all.

Dither plugins do not reaquire int output - you can losslessly represent
25bits of integer with IEEE float - you just need a known float->int
mapping.
