As reported at https://root-forum.cern.ch/t/bool-branch-becomes-python-object-with-rdataframe-asnumpy/64305

The logic at

root/bindings/pyroot/pythonizations/python/ROOT/_pythonization/_rdataframe.py

Line 302 in 477137c

column_type = "unsigned char" if column_type == "bool" else column_type

only considers the bool case, but not the Bool_t case, which is what a TTree branch holding boolean values will display to RDataFrame.
