Has anyone ever read lossily compressed data from an HDF5 file into ParaView? Is that possible?

HDF5 provides a long list of compressors and I am particularly interested in ZFP, so writing ZFP-compressed data into an HDF5 file is not an issue, but how does one load it into ParaView?

Would you recommend another way of storing ZFP-compressed rectilinear data? ADIOS2 BP4 works out of the box, but HDF5 seems to be more future-proof.
