When you start getting up near full well the response typically becomes non-linear so ideally you want to stay a fair bit lower.
In practice you'll almost always reach full well depth with your bright stars. Just make sure the rest of your data doesn't get too close. The conservative advice for flats is typically to target half well depth.
If you're really keen you can run a photon transfer curve and find out exactly how far you can push your sensor.
