It helps to track VO2Max if you’re into cardio. I’m assuming the watch can no longer measure it.

Most smartwatches estimate VO2Max using other data (mainly how fast you run/ride, your HR, and your weight). Blood oxygen level is not used for that.

I'm pretty sure VO2Max on the Apple Watch is measured using heart rate and not blood oxygen. It uses some algorithm to measure how fast your heart rate should be when you walk/hike/run.
