My tuned 1.4T is going to the dealer tomorrow for inspection. I have it in transparency mode so I suppose they can't see it, but what is the likelyhood that they would even check anything that might come across it? Obviously it will have to undergo emissions testing, but would that potentially show the tune?
Dealer likely to see my tune?

That's exactly what I did, but I'm paranoid!

If they have the latest global diagnostic tool instead of the Tech II, it's pretty easy to find even in Transparency mode.
The point is that they have to actually go looking for it. If you're going in for some warranty work or an oil change, don't worry about it. If your check engine light's on then they might go looking, but they need a reason to look. Techs don't get paid for speculation. Even then, the newer diag software is not exactly intuitive and I doubt most techs have even explored what all it can do.
Needless to say, their computer isn't going to start flashing a red background and screaming Tune Tune Tune Tune.

The other question is, if they did see it, why would they care?
The service department of your dealership isn't owned by GM, it's owned by your dealer, as a franchise. When they do a repair, they generate billable hours, which go either to you or to GM. If they deny your warranty they have to A) argue with you about it and B) risk losing you as a customer, not only will you probably buy your next car elsewhere, but you also won't keep coming in with this one generating billable hours. Meanwhile, if GM pays, well, GM is used to paying and they built your repairs into the price of the car.
Not to say some service departments won't gig you for every little thing they can, but just to say it isn't actually in their best interest to do so, so Most of them aren't going to look too closely.
Then you have people like me, who bring in a list of every mod and tell the service manager up front I don't expect them to pay for anything -I- broke, just for OEM parts that aren't my fault. If I can get coverage (and I have) then I'm pretty sure you can when all you have is the tune Chevy should have given you in the first place.

Why would GM do anything to hurt potential new sales in such a competitive car buying market? Even if 1 person got their warranty canceled I'm pretty sure it would be posted quickly on this forum of 3000 plus strong sonic and potential sonic buyers having negative backlash on GM.

Because modifying the ECM/TCM parameters outside of the tested and approved coding from the factory can induce failures and reduced engine/transmission life that they are not and should not be expected or required to cover. Adding 30 hp to the motor has its consequences, if you can slip it by the dealer then good on you, if not, you accepted the risk.

My last modded car was an 01 TDI golf. I had a big honkin K&N in the engine bay. Never came up. Even when it fell off and locked up my manual transmission in 3rd. Then again, never had anything engine related because those things are bullet-proof.
They have to prove that your mods were the cause of the damage, even if its something related.
