I think you're missing a key point here, the suggested photos are to support the description of the problem (like 'display freezes' or 'smoke comes out..'), not to support your possible claim of damage?
You're making the claim, the burden to support it is yours. You can submit a successful claim without photos, but having them increases your odds.
Again, not to say anyone here might scam them ('it wasn't scratched when I sent it in', 'I sent 2 sets of stems'....) but if you don't think that's a real part of Customer Service you've never worked on that end of things. If you're 'smart' (IMO, having done it several ways) you log and inspect incoming stuff, handle it through an established and enforced procedure, then send it through Production Test and Inspection (including a QC stamp) like it was a new product.
Mind you, even extreme measures as those don't eliminate problems, but they do cut them down. It's nice to be able to say 'it worked properly when it passed QC and shipped, I'm looking at the log....'.
A tough nut for sure, but IMO any thinking maker is very careful. If they goof something up (scratch or break something) the parts are right there, they're going to make it right. Shipping is, of course another matter (we'd use a Polaroid (high tech for the day) to photograph damaged or poorly packed boxes).
These days photos 'in case' make sense to me, whether or not the maker suggest it. Or accept the risk.
