No. The additional A/V content are: opening/ending without credits, promotionals and eventually the omnibus episode (for the series that had one).
The physical extras are: a few postcards and a booklet for each boxset. Unboxing video

Hellsing PQ is fine.
If you're referring to vick review, he mostly points out the fact that some of the old episodes looks meh (since they're upscales). His opinion is otherwise quite harsh because he was pissed of the multiple delays. There's no real apparent flaws or criticism beside.
Welcome to the NHK (Collector's Edition A4 - DVD - Black Box)
-72 pages artbook (A4)
-Five illustrations printed on cardboard paper (A4 sized)
It's mocking people magazines, the design is quite excellent imo.
Paying on dispatch also imply the store is keeping your credit cards details in the meantime, which I find extremly bothersome.
People need to realize shops are asking for payment upon ordering not because they want the money asap but simply due to it being infinitely more secure.
Usually the distributor (what you call the sub-licensor). It's not really regarded by the right owner (what you call the studio but most studio don't sell their animes) unlike an eventual dub.
