The TL081 has quite some noise, especially 1/f noise and also drift with the temperature. It depends on the application of the low frequency part is relevant. How important the voltage noise of the OP-amp is depends on the source impedance. The resistor in the feedback is usually large, but there is additional impedance from the input.
There is no need to get the input bias current below the planed for resolution, but it still helps to get a pretty low bias. By itself the bias would not be a problem, but it is usually quite temperature dependent and the temperature dependence is what can be limiting.
The OPA627 is a bit on the expensive side and rarely needed. If noise matters (relatively low source impedance / capacitoace) I would consider the OPA141 or rather similar OPA1641.
With a high source impedance one could consider lower bias, but higher voltage noise types like OPA377 or LMP7701 or similar - but these often only come as low voltage types an would thus need an added circuit to get 15 V out.
