How might Greenboy shells have changed Jutland?

What difference might Greenboy shells have made at Jutland?

They could have sunk severely damaged German ships such as Seydlitz and increased German capital-ship losses, making a German tactical-victory claim much less plausible.

Badly damaged German ships survived because of exceptional crew effort, so their return to port should not be confused with casual resilience. Better British shells might have sunk Seydlitz and perhaps other German capital ships, changing the balance of losses. Britain could replace ships more readily, while Germany faced stronger army demands on its resources. The counterfactual connects ammunition quality with industrial endurance.
