Some thoughts here...
As mentioned many times, even though you hold a 107 certificate, you could still fly under 101.41. In doing so there is no "light switch" or "siren" to the world announcing what you're flying under, just follow the rules of the applicable regulation you choose. If this doesn't sit comfortable with you, log all your flights to show what flights were under 107 and 101.41.
Now here's a loophole - suppose you hold a 107 certificate, live 3 miles from a class G airport and want to just fly around, there is nothing preventing you from attaching that seemingly recreational flight to 107 activity such as "flight proficiency," "equipment testing," "camera adjusting," etc., all part of you using your drone for "commercial purposes." Again, if you have concerns a simple log book provides clarification if an issue ever arises.
