Those screencaps look really nice!
We all may want specific titles from Warner that we like to chase them for but what they do release is almost always first class and among all the studios makes them numero uno with regard to the combination of quality and quantity that they put out.
The original post just mentioned Warner as a favorite boutique label. But even if we take Warner Archive it just looks like a different distribution approach to me whereby Warner maximizes returns on titles that they think will sell below a certain number of copies on Blu-ray. To my knowledge...
The biggest Hollywood studio of them all is now a boutique label?
Not sure I agree with that classification but I look forward to get my Blu-ray of Bad Day at Black Rock!
