Hi Miles,
Not sure to understand what are you referring to with "antialiasing"
property.
Anyway, did you try to set a different interpolation in WMS?
>From the GUI, you can select the WMS from the Services list and switch the
*Raster Rendering Options -> Default interpolation* from *Nearest Neighbor*
 to *Bilinear *as an instance.

This is what I get on a sample GRIB dataset when changing that property.
Left side = Bilinear interpolation; Right side = Nearest neighbor


​Cheers,
Daniele
