How curvy/bendy can a 3D blank be?

Have been interested in using vacuum heat press for a while, but more from a curiosity point of view at the moment, as I can't see the benefit to our business for a machine that can mainly only do phone cases.
But, out of interest, how well do they cope when printing to things that are really curvy - I assume that using the transfer film will be better than transfer paper for curvy things.
I am thinking, like, if you had a polymer material or coated sphere, like a Christmas bauble, could you sublimation print it successfully - I'll assume you'd have to do it as two pressings, with each pressing doing half the sphere, or would the curvature be too great for there to be a good print without creases?
Trying to work out what the limitations of sublimating using a vaccuum heat press would be, or how much you could push it to be creative.

Laws of physics. Flat image on sphere, either requires crease or distortion due to stretch. Hmmm fat Santa with small head and feet...ok. Aunty Flo the same way...perhaps.....perhaps not.
