Correct. The overall performance vs. frequency curve is very similar for RX and TX.
The way this is handled in calibrated test equipment is that firmware adjusts the gain based on configured frequency and based on stored calibration data. This compensates for non-flat frequency response, but it does so at the expense of calibration effort and maximum power at frequencies at which the hardware performs better. HackRF One is uncalibrated test equipment.
