O2 contents where much higher some 60 to 150 millions years ago. Interchange
capacity of the lungs of the massive moving mussel mountains (Dinosaurs)
would  not have been able to support this easy without higher O2 content.
Now the other side is that here in Bolivia at 3500 to 4500 meter above
sealevel your oxygen content is much lower ( 4% lower) then at sea level and
those guys here do marathons every day running 600 meter height difference
in 20 km track from 3600 meter sea level to 4200 meter sea level. You should
see that. Don't have the feeling that there is any perishing going on, they
thrive on the lower oxygen.
Well I am a heavy smoker 2 packs a day and after a 2 weeks adaptation feel
very well in 4000 meter although my oxygen access should be much lower then
from a non smoker. If you do experiments in the lab rising 5 % the oxygen
content in a closed environment ( reactor) you still can not set fire on a
soaking wet biomass like a 2 week old branched of a tree.

There we have to get still better numbers then just tell tales.

No offence meant

Best regards Nikolaus
