My clutch fluid was a mess at 9 months 2,800 miles from new. Clutch was making a strange noise taking off in first gear so I took the cap off. The fluid looked like cooking grease like there was moisture in the system (pic below). I normally use the "Ranger Method" to change clutch fluid out twice a year, but since the car was new I didn't do it. I swapped the fluid out using the Ranger procedure the next day and the problem is gone. Clutch fluid looks normal again, but I'm going to keep a close eye on it. I read that in C7's the clutch fluid line runs close to the exhaust which is why GM calls for the use of DOT 4 and recommends changing the fluid out at 36K miles.
On my '08 Z51 the clutch stuck to the floor once and after changing the fluid out using the above method, I never had the problem again. Video is of a C6 but same procedure for the C7.
I used the Ranger method on my C6 at every oil change. Traded car after 14 years and 65,000 miles. Never had a clutch problem. It takes several clean ups to get the fluid clean , but once clean it stays clean if you continue replacing it.

I had the dealer replace my clutch fluid at 7k. It looked like chunky soup. I’l keep it maintained using “Ranger” method from here on out. It gets dirty fast.
