So. Since wavelets here are just filter banks, equivalent to fixed/non-varying convolution+downsampling blocks. Could you learn an improved set of wavelet filters to improve this result?

That is indeed possible, though at a computational cost. The Haar wavelet can be implemented very efficiently because of its simplicity.

Please see Appendix F, where we shortly discuss other wavelets and their added computational costs.
