Is the only reward you get, the fees from transaction?
I've seen some pools are incentived additionally by the project (usually by new tokens that create a pool), in the farming rewards style. Obviously, unreliable on the long term, as always.
Also, I think we receive some platform tokens from Meteora (or an airdrop), not sure yet, by using the platform.
But trust me, those transaction fees, for well-chosen concentrated liquidity ranges. get really interesting. We are talking hundreds of percent in APR in my case yesterday, although it doesn't make sense to calculate APR, since you usually need to withdraw and change the range often.
