If HQ XX7 got armrests standard it is not a direct Sandman component. Unless it was standard with XS6 (buckets), which gave B code trim. Then it makes sense. To be honest i've never really taken all that much interest, but it is an interesting point. Not a Sandman identifier as such, any more than B code trim is anyway. I'll look further later. Brochures will always show the higher level interior, and be careful of trusting them too much as a reference.
