Let's say I would like to know all the Rules that apply to PlotTheme->"Detailed". I tried

Select[FullForm[Plot[x, {x, 0, 1}, PlotTheme -> "Detailed"]], Head[#] == Rule &, Infinity]

but I get the Error/Warning that FullForm was called with 0 arguments, which doesn't make sense to me. What would be the correct way to do this?

    $\begingroup$ You should use Cases instead of Select like this: Cases[ Plot[x, {x, 0, 1}, PlotTheme -> "Detailed"], x_ /; Head[x] === Rule, Infinity ] $\endgroup$

    $\begingroup$ In general if you are looking for rules you would also need to check for RuleDelayed, e.g., Cases[Plot[x, {x, 0, 1}, PlotTheme -> "Detailed"], x_ /; (Head[x] === Rule || Head[x] === RuleDelayed), Infinity]. In this particular case that only adds one DisplayFunction :> Identity $\endgroup$

You can get the options associated with the plot theme "Detailed" using the (undocumented) internal function Charting`ResolvePlotTheme:

Charting`ResolvePlotTheme["Detailed", Plot] // Column

If you need the options for the legended graphics object produced by

 plot = Plot[x, {x, 0, 1}, PlotTheme -> "Detailed"]

you can use Part:

Head /@ {plot, plot[[1]], plot[[2]]}
{Legended, Graphics, Placed}
plot[[1, 2]]
