Rob ter Horst's (The Quantified Scientist) test results compared against a fingertip pulse oximeter—which include at ground level and on flights—seem to indicate that they're okay for detecting whether your SpO2 readings are normal/abnormal. Basically it seems that if you get a one-off abnormal reading then it's possible for it to be a false positive, while you're unlikely to consistently get false positive results. See the video for the Apple Watch Series 6 [0], and Series 7 [1]. There's also tests for the Series 8 [2], although it doesn't include data collected in a low oxygen environment.
