Would Dogger Bank change German ammunition lessons?

Would heavy German battlecruiser losses at Dogger Bank change the ammunition-handling lessons Germany learned?

Yes, but the larger effect is that Germany loses its scouting and raiding arm, forcing the High Seas Fleet into a passive posture and probably preventing Jutland.

The answer separates tactical experience from institutional learning. If First Scouting Group loses multiple battlecruisers at Dogger Bank, Germany does not receive the same later evidence about ammunition handling because its fast arm has been destroyed or crippled. More importantly, the High Seas Fleet loses the force needed to lure and hold a detached British formation. German operations would likely become much more passive, making a recognisable Battle of Jutland unlikely.
