Kind of but not really. DDR5 splits your typical 64-bit channel into two 32-bit subchannels meaning the bus width is not increased. These subchannels are not always advertised because it's a just a feature of DDR5. Actually adding more channels increases bus width, which is what meaningfully improves memory bandwidth.
