Yes, I have, and you can too if you have a power meter (and if you're using WKO4 it sounds like you do).
The exact difference will depend on how wide your handlebars are, how deep the drops are, how high your hoods are, and how bent your arms are when you're in the drops or on the hoods.
If you have a power meter you can test this yourself with the "Aerolab" feature in Golden Cheetah.
And just for the sake of 'post compaction', WKO is now advertising "elevation corrected power'. What are they doing here? Are they maybe adjusting your input power to reflect the somewhat reduced power requirements (for a given speed) that result from lower density air at higher altitudes (lower Cda)?
I think they're mostly focused on the physiological effect, i.e., the reduction in power production at higher altitudes.
