The bandpass circuit occurs only near the cutoff frequency to boost the response so that it has flat levels at low frequencies, -3dB at the cutoff frequency instead of a droopy -6dB and a sharp 12dB per octave slope at higher frequencies. Above the cutoff frequency both RC networks are lowpass filters.
I don`t understand your position.
A bandpass is a bandpass - full stop.
Just one question, which can be answered with yes/no:
Do you agree that - between the ouput pin and the non-inv. input of the opamp - there is the classical four-element ladder network C1-R1-R2-C2 ? And this is the well known RC-bandpass.
How can you say that "Above the cutoff frequency both RC networks are lowpass filter
At first, we don`t have two RC-networks because you are not allowed to separate them, because they influence each other.
Secondly, the series cap C1 - of course - has highpass properties. I don`t think that you will argue against this.
