Internationalization / Localization of preset constants in climate component

I’ve built a custom component for my fireplace and the only thing left is to have a human readable name for my preset flame_effect. Currently in the ui the presets dropdown has None and flame_effect - which is inconsistent (why does None have a capital?). Ideally I’d map flame_effect to Flame Effect.

I’ve read the documentation on Internationalization but I’m still not sure if it’s possible to provide localized names for these sorts of constants. I’ve tried both strings.json and .translations/en.json - I’m just not sure what structure / keys I would need. Any guidance / help would be appreciated.
