This 6.19% is mostly real staking / lending yield (~5.85% of it). Only about 6% comes from token emissions. It is single-asset, so there is no impermanent loss to drag you below holding. It can still fall, but it isn't a disappearing subsidy.
Real fee/staking yield: 5.85% · token emissions: 6% of the headline.
No impermanent loss here — the ~5.85% is real income on the very asset you'd be holding anyway. Only any emissions portion fades.
