Generating DotPlot using "split.by", Average Expression fix

[RosalinSimpson]

The current DotPlot examples for v5 show that when using split.by you will only receive the Percent Expressed figure legend.
When using this function myself, if I specify the colour during the DotPlot function with "split.by" it will generate the Average Expression legend. This is using the code: DotPlot(seurat_obj, split.by ="Treatment", cols = "RdBu", features = genelist)

I noticed an old issue post about a work around for this and when following this method I receive the same figure as the code I used above.

The same expression patterns are shown when I examine VlnPlots for the same genes, so I was wondering if this is suitable? Is the Average Expression generated for the above figures "truthful" or are they not accurate when specifying the "cols" in DotPlot.
