It may not be anymore, but it used to be. I bought a 65" Samsung back in 2012, and had to sign to receive it. From the truck through signature, the delivery agent held it like a giant iPad in portrait mode, pinching the long edges of the box. It had a clear "this end up" arrows... pointing sideways.

When I turned it on, there was a big dim spot on the top edge of the panel. It had to be exchanged.
