Two parts to that, on the Mercedes element they would have tested the DRS gap prior to the session and should have some record of that happening. They took Bottas' car into scrutinising as well post session so they'll be comparing the two wings on the cars. Note that Red Bull were raising this with the stewards prior to the session as well, so they had some suspicion from FP1. So the stewards will be looking at whether this was either intentional (ie. done prior to the session) or unintentional and occurred during the session. Either way, I'm expecting a DQ for Hamilton and a pit lane start for the sprint race.
I think the Max element is just a storm in a tea cup and being used by Mercedes to clip Max's wings, as they're preparing for a DQ for Hamilton by the stewards. He wouldn't have made any difference to the car
