I first ran the Adafruit_ILI9341 example on ILI9341 display with your defines:
ILI9341 Test!

This is with the Adafruit_ST7796S_kbv example:
ST7796S_kbv Test!

Note that the registers are not being read correctly.
This is from Bodmer's TFT_graphicstest_one_lib:

This is my Read_User_Setup output:

Display SPI frequency = 27.00Yes, I think that it would be a good idea to "decode" the pins and SPI interface into something human-readable.
