AD7779 How does the number of channels used affect ENOB?

Hello, I am looking at using the AD7779 in a load cell application. From the datasheet, it looks like it should work well. However, I intend on using 6 channels, and the datasheet often does not state how the number of channels affects the specifications. Table 11 on pg. 33 of the datasheet gives a range of ENOBs for various output data rates and signal frequencies. Do you know if these are per channel specifications, and if not, how would you find out the approximate per channel ENOB for this ADC? Thank you very much for your time,
