op amp models
Typically OP amp models are functional ones, e. g. using a differential input stage and analog behaviour blocks for the rest, mainly to limit the node amount and speed up simulation. Tranistor models are temperature dependant to some extent, e. g, BJT have a systematic Vbe and gm temperature coefficient. Other parameters are not temperature dependant by default.
Default modelling of temperature effects would require the existence of a systematic dependency, but many temperature effects are rather accidental, e. g. offset voltage coefficients.
Sometimes, manufacturers are providing special models for Monte Carlo simulation of parameter variation, they typically also assume a maximal temperature dependency for some parameters.
Generally, a simulation model should not be expected to represent the complete behaviour of the real part. The primary source of specified data is the datasheet. It's unlikely (but possible anyway) that a model contains data missing in the datasheet.
If you want to model certain parameter variations, that are important for your application circuit, you should extend the model respectively or add external elements representing this behaviour.
