QUAD SPI while using Audio Shield?

I may be missing something here, but I don't see anything about quad SPI with this display? I see their normal 3 wire and 4 wire SPI options.
I do not have this one of theirs but do have some of the RA8875 and an ILI9488 displays and have connected them using 4 wire SPI, which is normal for many of our displays, where we talk about using MOSI, SCK, CS, DC in some cases MISO (If you can receive any data back from the display).

Note: I don't know if there is a Software library yet yet that works with this display.
Sorry, I think I got misled by an Ebay listing. So much for due diligence.

They just arrived though and look very very nice. Hopefully regular SPI will not be too slow. Hate to tie up too many pins with the parallel modes.
