Thanks to let us know your requirement.
In fact we support the jpeg2000 via LizardTech library.
It mainly works for 8 bit and 16 bit, for 32 bit that should be the types of RGBA, GrayScale, the 3rd part library cannot complete support to read all the bands.
And in fact we have a little confused about your question, you mentioned the 32bit and 36bit, so what's the exactly bit?
If that's 36bit, we don't support that.
But if possible you can upload your jpeg2000 file, our developer can did some test to see whether we can render it.
