Given that 37s weren't ever done in chromatic blue (only a few hydraulics were), no blue 37s were known to have small yellow panels, 37s werent overhauled at Swindon and nothing was blue in 8.64 apart from D1733, I doubt it. In fact I doubt it's even a 37 - it's something blue admittedly, but it's behind a sliver of reddish brown which is probably the corner plate of a High Goods wagon
I'd concur with that Paul, it's another example of what I said recently about modelling a preserved loco being akin to modelling another model.
The Dursley shot is perfectly typical of an 'in service' D95xx number whereas the preserved one (like many preserved locos), isnt. Before anybody jibs at this comment, I have the greatest of respect for anybody involved with such restorations, but it is unfortunately a fact that some loco's livery details are not faithful replications of how they were in service
Hardly a show stopper though, given that we'll not all want to be running D9500
