STM32H730 fails to verify
Open source flash program for STM32 using the ST serial bootloader

The STM32H73xx range is currently not included in the devices table. If commented in and filled in for an STM32H730, most functionality is correct. Writing a file without verifying works correctly. When adding the -v option to verify writes, it always fail to verify on the second page. Reading the contents of the flash back via JTAG shows the write of the second page was corrupt.
As mentioned, it is possible to write without verifying, read the contents back and verify outside of the stm32flash tool but is not possible to verify with the stm32flash tool.

Interestingly there is a very similar problem with the st-link tool. https://github.com/stlink-org/stlink/issues/1369
