As highlighted in this issue (https://github.com/polkadot-js/apps/issues/9860) the Polkadot-js UI is based off the default Polkadot staking parameters which are different to ours. This means that the inflation shown in the polkadot-js UI is incorrect but more importantly the staking reward returns are incorrect.
We are being asked by 3rd party providers to verify APY rewards but don't currently have anywhere that displays these correctly.
As there are many, many chains this is not something the polkadot-js maintainers will do for us.
Solution
It seems that someone with the requisite technical knowledge needs to make a PR to the polkadot-js repo which gives the correct parameters for our specific chain and this would hopefully be trivial to do.
