The TLC5955 contains a 769-bit common register. Serial data is written to the common register by setting data to SIN, and toggling SCLK.
When serial data is continuously written to the first device in a chain of TLC5955 devices, SOUT does not output the serial data. Are any other signals involved writing to a chain of TLC5955 devices besides the SIN and SCLK signals? From the spec sheet, understanding is that by continuously writing data to SIN, the data will be shifted out of the SOUT pin.
